I looked around for a tool holder for the accessories that came with the Lulzbot Mini. When I did not find one that I like, I decided to design one myself with FreeCAD. Some of the design goals are: tool-less installation and removal out of the way of the acrylic enclosure out of the way of any moving parts maximize functionality while minimizing filament weight no support generation required Available slots: 25x3mm (clam knife) 25x10mm (pliers) 18x9mm (dial caliper) 12x8mm (tweezer) 30mm dia. (fat glue stick 22g/0.77oz) two 10mm dia. two 1/2 inch dia. (Sharpie marker) general-purpose pocket Installation: push bottom down at an angle onto the Mini's frame push top inward to snap into opening slide toward the front to engage clip I printed my copy with 2.85mm filament, infill at 20%, and shell thickness at 1mm, the total filament weight is 97 grams.
