Description
A sleek, modern desk organizer for quick access to the tools I frequently use when designing and making.
The STL file is designed to fit iGaging calipers, the Adafruit PCB ruler, a Pentel Click mechanical pencil, and a Pentel eraser. It should fit most average calipers, any writing instrument with a tapered tip, and other erasers and rulers. I have included the major dimensions of the slots, and .f3d and .3mf files so you can edit to your own liking.
The bottom has 8 18mm holes to glue in weights. These should be easy to print without supports as the surface finish isn't important on the inside. Steel washers are relatively cheap and work great, so do lead fishing weights. I believe with the height of the calipers this would be really tippy without any weights.
