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.
