As the title says. I'm new to 3d printing and I'm looking for tips on how make two parts fit together nicely. I've read 0.4mm clearance between the two parts modelled together is a nice rule of thumb.

I typically model for 0.5mm tolerance between firm fit parts.

Before you can bank on this, you need to see how tight your tolerances are on the printer. I used the Maker's Muse tolerance test device to figure out what my printer could achieve.

It's worth the $2 for the model...

There are lots of free tolerance tests on thingiverse or printables.com too
