I did a bear mod of my mk3s a while back and them came across a CoreXY conversion that uses a chunk of the original parts through ProosaXY. I swapped the axis steppers as I would have needed another z motor anyhow. Anything I had to cut down I bought new, but things like rods, bearings, power supply and bed are reused. I had a chunk of my mods done a few months back, just didn't have a chance to do assembly until the holidays.
Made some mods for my my setup, I like to try keeping similar parts & setups for my printers to make spares and servicing easier, so made a carriage that could accommodate a voron tap carriage w/ a canbus board on the extruder, lose a bit of print space but I'm fine with the tradeoff. Also made front idlers inspired by VoronBFI
Also did up a tophat and panels, they're partly printed, partly cut from hdpe & wrapped with aluminum tape, was trying to vaguely emulate the look of my aluminum composite panels on my v2. I had space to add some basic insulation so did that. I did up a door using the frame from the mk3s as the front and hardware from the ClickyClack Door. I still need to tune it and setup slicer profiles, some of the panel clips are mismatched as I used what I had on hand, will swap for all black or orange ones later. Power supply needs a better mount, but will work for now.
Apologies as the pictures aren't great, took them last night when I was doing a (really rough) fast benchy as a first print.
