Pimoroni Badger 2040 Case

A 3D printed case for Pimoroni's Badger 2040 e-ink RP2040 badge: https://shop.pimoroni.com/products/badger-2040 Note I broke one of my buttons off with an earlier badly measured version, but this version is good :-) It's designed to be held together with 4 M2x10 bolts. The OpenSCAD file is parameterised so you can change the bolt length or make more space on the back for components/add-ons/batteries. There are versions with holders for CR2032 coin cell batteries in the back. I'm not totally happy with the battery holders, but they do work. I've used copper tape to connect the negative terminals, and some LED leg clippings to connect the positive terminals together across the row (on the 3 battery version), held on with a dab of hot glue. See the pictures. I've printed with supports for the bolt recesses in the front face, and for the battery holders. It's a bit tricky to get the support out from the battery holders, but it's doable :-). Also it's a bit tricky to get the batteries in/out of the holders, but again, it's doable :-) There's a hole for the LED on the front - I like to put tape across the hole on the front, put some hot glue into the hole from the back, and then remove the tape. It makes a simple, neat light guide. There's reports on twitter that the Badger can run off a single coin cell, but I couldn't make that work with the factory code; so I added a 3-cell version which works for me (TM). https://twitter.com/mdb036/status/1499145487659814915?s=20&t=vGUyvGEO2Qrjtevz_R_Rww
