Modular Tube Storage Rack by DrUsual

Last crawled date: 3 years ago

Everyone who dabbles in electronics is familiar with the annoyance of storage boxes with compartments that don't seal up to the bottom of the box, right? Small parts like resistors just roll under the "walls" and get all mixed up. I wanted something to organize resistors in enclosed compartments. There are some cool sewing organizers, systems of complete boxes within a larger box, but those solutions are no fun -- they don't involve 3D printing.
The actual containers here are clear plastic test tubes I bought from Amazon, link below. I've uploaded models for two versions of the tube holder, a single holder and a fiver. Both styles have connecting holes; just print the "connector" model and put them together.
The connecting holes are d=10mm and to be flush on the back the knobs on the connector straps are h=2. The knobs are d1=9.25 and d2=9. While they do pressure fit, I didn't dial them in to truly "lock." My intent was to have them just provide stability for each other while lying in a shallow tool box. I'd suggest gluing them together permanently if you're going to carry a box around or mount this vertically on a workbench wall, pegboard, etc.
The OpenSCAD file is also uploaded in case you'd like to make connectors that span more than two holders, create 3-packs or 10-packs, whatever you like.
Next step is to find or print a box that a bunch of these will fit nicely in.
