Open chain
thingiverse
16 jan 2018: Updated the clip to have no sharp edges. Updated the stepper connection part to better fit with the MKS base box. Original post: I designed another openable chain as the ones I've tried didn't work, they needed to small parts or simply didn't work as I expected. The clip on the chain is slightly bendable & stretchable. This makes it very easy to put them on the chain, yet they don't fall off. Print in PLA but PETG & ABS make the clips more resistant to enthousiastic bending :-). Scale the clip down or up with 0.3-0.5mm if your printer accuracy is not the same as mine :-)
