Hello. I was also trying to convert Prusa i3 MK3 to coreXY. Maybe you can be inspired by my approach and take some printed parts. The main difference is use of one extra ALU frame and no extra ALU profiles. The frame is much more rigid and has very low skew compared to bolted ALU profiles. Also the power supply holds the frame. Unfortunatelly, I haven't finished the Z axis.

Fantastic work! I always wanted to transform my prusa into a corexy but ,while waiting to have time and money, I changed the standard frame with the bear one.
Do you think that, with some modifications, I can reuse the bear frame?

I am looking into building this for my Prusa MK3S+, but I have a few questions first:
This is (will be) a custom-built Prusa MK3S+ made from the frame left over after I did the Bear Upgrade. My only significant changes were using 0.9º steppers on x and y (high torque on y) and making a custom dual extruder head.

• What parts need to be removed/modified from the original Prusa to do this upgrade (so I don't buy them)?
• Where do you buy your aluminum extrusions and DIN rails (I couldn't find the right lengths on Amazon or Alieexpress)?
• What's the status of the build instructions? I don't think I'll be able to build this without them, as this will be my first time messing with CoreXY.
