Please excuse my crude Fusion360 skills, lol. I made the “Right Spacer” shorter for clearance and the “Holder” larger to fit. opened the holes to 10mm. extended the trigger out and up. you may or may not need a screw. The bucket is the same. Print it like the orientation, and everything fits perfectly. I printed with 100% infill and .2 layer height. Also, wrap the bucket in something that the filament wont stick to. Use a rubber band or spring for tension.
You do lose 5mm of X-axis. The MK4 is all proportioned differently and this was the best I could do. But NO PURGE BLOCK needed! Which means if you don't have a color change until layer 72 or so, you don't need to keep building the block for level 72. Huge savings in filament. and space!!
Heres a Link To a quick video showing it working.
SUPPORTS:
Holder : supports everywhere
Spacer: supports from build plate only
Trigger: no supports
Bucket: supports from build plate only

The author remixed this model.
I loved this setup from Forfelet on my Prusa MK3. But I just upgraded to the Prusa MK4 and it doesn't fit. The z-axis rods are 10mm and the X-axis holders are bigger and have less clearance as well.
