Folger Tech 2020 i3 Chain Mounts

thingiverse

I wanted the user's chains on the back instead of underneath the carriage, so I printed those separately. You can find my design for these chains at thingiverse.com/thing:921162. To attach the heat bed mount, I used a M3 screw and nut on the front and a M4 screw with a T-Slot Nut on the rear. Don't forget to drill new holes if you want to upgrade your hardware. I printed one chain at a time using 1.75 PLA. ABS would be a better choice because it needs some flexibility for a snug fit, but my chains are a bit stiff due to PLA's rigidity. I connected them immediately after the print was complete.
