Y-parts for Zaribo MK2.5, including a bed chain solution

thingiverse

I'm still working on my STUVA-enclosure; I didn't have enough room inside it. So I decided to do something else instead; I made a cable chain while I was at it. This cable chain is designed for my Zaribo MK2.5 12V bed. To make it, you'll need 20 links. One end fits into a 2020-extrusion and the other end has M5 screws that go into those same extrusions. The rest of the parts are held together with M3 screws. I've included all the necessary rod holder parts: Y-motor-holder and Y-tension parts. Just remember, if you're using your printer as an MK2.5, you'll need to put the end switch in the motor holder. But if you have an MK3 printer, simply swap it out with the provided archive files for Fusion 360. The Y-tension system should work just fine for both sizes of pulleys. To get the best results, use a screw that's been threaded only up to the first 14mm; any more threads and your pulley will start to make noise as it climbs them - trust me, I know! As for the Y-belt holder, you might need to do some fine-tuning to get the belt lined up perfectly horizontally. But don't worry, mine worked just fine even after I printed it with no adjustments. I've included all the necessary archive files from Fusion 360 so you can make any adjustments you need to fit your printer perfectly.
