I’ve been using the springy OpenLOCK clips found on Thingiverse with great success – https://www.thingiverse.com/thing:3367267.
Would it be possible to create the clip caps so they using springy clips? I find it very difficult to use the solid clips and have even broken a few of the clip separators in pieces (depending on the brittleness of the filament brand) trying to plug them in. While I’ve also broken the occasional springy clips, those are much easier (and cheaper) to replace than the bigger pieces these clips hold together.
