And today evening I will print a case for my recently upgraded trusty old iPod:

Update:

After a few changes the second prototype came out great, files also available for free now on my printables:

I read Pinterest instead of Printables at first and got ready to shit bricks and throw tables. What am I gonna do with all these bricks and tables!?

That honeycomb design is sick, almost makes me wish I had an iPhone :D

Xiaomi Poco X3 NFC. Doubt there's enough people running around with this this that it's worth putting time into making a case for it :D

[–] [email protected] 9 points 1 year ago (1 children)

Will this one fit your phone? If yes, I can modify it for you how you like ;)

[–] [email protected] 6 points 1 year ago (1 children)

That sure looks like it fits! If I may make a request then, I'd love that with the full honeycomb back like that yellow case.

Please and thank you, and let me know if I can send you a fiver somehow :)

[–] [email protected] 20 points 1 year ago (1 children)

Here you are:

Let me know if it fits. Would love to see a picture :)

Better donate the money to a charitable cause. I'm doing this just for fun.

[–] [email protected] 7 points 1 year ago (1 children)

You rock, thanks a bunch! :)

[–] [email protected] 9 points 1 year ago (1 children)

My pleasure! I just added a second version with the lanyard holes ;)

[–] [email protected] 5 points 1 year ago

I'll send some pics once I've had it printed :)

[–] [email protected] 15 points 1 year ago (1 children)

This is how it starts. Next thing you'll know you'll be optimizing phone shapes, learning physics about drop protections, and soon starting your own case company.

[–] [email protected] 5 points 1 year ago

You might be right, I looked up a lot how Spigen gets their cases durable recently in order to create a really rugged version :D

[–] [email protected] 14 points 1 year ago (2 children)

Word of warning, 3d printed cases are a bad idea. The plastics don’t actually absorb the impact like a real case would, and so they break often and don’t actually absorb the impact and protect your phone. Every time I’ve used one I’ve ended up with damage.

[–] [email protected] 17 points 1 year ago (4 children)

Did you use TPU for the prints? If you used PLA, that really was a bad idea. With TPU my drop tests (not on purpose) were successful and the phone without damage everytime (so far)

It depends how thick and soft the tpu is. If you have a thick enough and soft enough case, it will absorb an impact. Just like silicone cases do. And they are also solid.

[–] [email protected] 10 points 1 year ago (2 children)

Those look super nifty. It makes me wish I had a printer.

Most libraries have a printer you can use.

BTW… In the process of designing these there were made a few prototypes. They all are not perfect, but if someone (from Germany) wants one, here is my stock :D If you have questions on a specific one just ask. I would give them away for shipping+packaging cost.

iPhone 13 (regular):

  • blue Mama Version
  • big MagSafe Cutout Bumper

iPhone 13 Mini:

  • slim hex back yellow
  • thicker round hex cutout transparent
  • rugged small hex back yellow with grip pattern

iPod Classic 5G:

  • neon green case with hex back

How soft/bendable is it compared to silicon cases?

[–] [email protected] 5 points 1 year ago (1 children)

It's flexible enough to get a phone into it, but it still feels pretty stiff, depending on thickness and infill settings. It's flexible but not really stretchy.

[–] [email protected] 5 points 1 year ago (1 children)

As long as it's flexible enough, it's probably enough to protect the phone when falling on a hard surface. Just another reason to get a 3d printer. I'm having a hard time finding cases that I want and never thought it's possible to make one using 3d printer.

[–] [email protected] 4 points 1 year ago

I threw mine a couple times now with the new case, so far it’s doing a great job (using the neon green one with the blue lanyard for myself). But it highly depends on the type of case you print or to be more precise on thickness and buildtype. If it’s thick enough and protects all the edges, you probably will be as save as with a usual case you would buy (at least that’s what I feel right now after I designed and printed these). But if you print one, that’s very thin, then your phone might get damaged when dropped.

You’re absolutely right. I had the same problem. Always wanted the case I am using right now, but I just wasn’t able to find one. Feels like a bit more freedom right now. And for the price of one good case from Amazon I now print multiple. But yes, I paid for the printer, material and electricity. If my calculations are right, my printer paid off already after I printed a holder for my wife’s hairdryer. If I would have bought one, it would have cost me about 130€, absolutely insane. My printer with all upgrades cost me 300€ by now btw. So definitely get yourself one :)

Ah that's way better than I expected!

[–] [email protected] 6 points 1 year ago (1 children)

I've had pretty good results with TPU as well. However I recently found some filament called soft PLA which has been similar structural properties to TPU, but seems a little more forgiving with print settings.

[–] [email protected] 2 points 1 year ago (2 children)

Interesting, could you share a link please?

This is amazing! Well, great excuse to buy more TPU :)

[–] [email protected] 5 points 1 year ago (1 children)

Oh you are so right :D I bought 3 rolls last week… Using this one for my cases btw:

How well does the Lego one work with actual Lego bricks?

[–] [email protected] 6 points 1 year ago* (last edited 1 year ago)

Perfect! I used the actual Lego dimensions. Made that one for a friend who owns a Lego store

Edit:

Didn’t upload that one yet. But I can if someone wants it ;)

Edit: spelling

Enjoying the paracord, I might give this a go on my current case. How does the connection look like?

[–] [email protected] 6 points 1 year ago (1 children)

I tried to make it easy to print, here are some more detailed pictures:

[–] [email protected] 3 points 1 year ago (1 children)

Damn, I was hoping that was a jump rope.

[–] [email protected] 4 points 1 year ago

No, a jump robe would be a bit too thick I think. But you can get cheap „Paracord“ on AliExpress, Whish or Temu. Pretty sure on eBay and Amazon too (even though a bit more expensive).

How much more difficult is it to print TPU compared to PLA?

[–] [email protected] 5 points 1 year ago

I would say that depends on you, your printer and the used filament.

On my Voxelab Aquila out of the box with official slicing Software I could print PLA without issues, but with TPU it would have been impossible. Now I use Astroprint.com for slicing where I control print settings in more detail than it would be possible with Voxelab’s slicer. So that was the first step to take. Also I upgraded my printer to DirectDrive and DualGearExtruder. I then needed a new fan shroud, because the one I used before didn’t fit anymore. Then I had to learn about e-steps, because somehow I went into Unterextrusion (after switching to the dualgear Extruder you need to get the e-steps set new depending on the new extrudergear thickness. Luckily it was mentioned on the package it came in). Then the TPU started wrapping around the extruder gears. Turns out I printed too fast and so on…

Long story short. Depending on your printer, I would suggest at least switching to DirectDrive if your printer doesn’t have it. Also print very slowly, like 20mm/s slowly.

[–] [email protected] 3 points 1 year ago (1 children)

What orientation do you print these in? Looks like you'd need supports and I've had trouble getting nice finishes on the side that needs the supports. I've only printed with PLA though.

[–] [email protected] 3 points 1 year ago* (last edited 1 year ago) (1 children)

I printed most of them laying on the back to get this nice PEI printbed finish. The only one I printed upside down is the LEGO one, because I was afraid the back would look ugly if supports where on it. Of course you could print all of them facing the back up, so the „ugly“ supported sides are inside. You obviously will need more filament that way because of the supports, but it should work just fine.

BUT…

I highly recommend printing these in TPU, not PLA. I don’t know if you will even be able to get your phone in these, as they get a bit around the phone and PLA is not really flexible. And even if you get it in, it will possibly brake fast and not protect your phone they way it should.

Edit:

Here is how it looks after slicing. The brighter parts are supports.

[–] [email protected] 3 points 1 year ago (1 children)

Oh of course I'd print them in TPU. I was just saying that because I have no experience with printing it and if the ugly side is as ugly with TPU. That's my only concern with printing a phone case. I'm pretty new to 3d printing so I only just learned some the limitations and the ugly side of things lol.

[–] [email protected] 2 points 1 year ago (1 children)

Ah okay, then I got you wrong. I edited my last comment with a picture that shows the supports, so you get an idea where the „ugly“ parts would occur. I made good experiences with gas lighters (not normal ones, the ones which flames look a bit like a blowtorch). With these you can carefully warm the TPU and try to make the ugly parts a little more beautiful. You can as well use a clean soldering iron to iron the ugly parts a bit more flat.

[–] [email protected] 3 points 1 year ago (1 children)

I see that. Doesn't look too bad. Appreciate the picture. I'll have to do some experimenting trying what you've suggested.

Have you tried printing with infill but no top or bottom layer? You can get a pretty nice look with stuff like exposed gyroid infill.

[–] [email protected] 2 points 1 year ago (4 children)

I did this for a few inserts for like glasses holders and stuff, but not yet for smartphone cases. Wouldn’t it then also expose the top of the edges? Also I think it would probably collect very fast, very much dirt in my pockets :D
