SMD Storage Cartridges with DIN-Rail Dock

Remixed from Kadah's "Parametric SMD Stacking Magnetic Mini Spools" on Thingiverse: https://www.thingiverse.com/thing:4609897

I resized the spools to hold 1000 0603 SMD components, and made a dock for them to clink into. Magnets (https://www.mcmaster.com/5862K101/) are placed in the rear of the cartridges to stick to a 1" x 1/8" x 111.9 mm steel bar (https://www.mcmaster.com/8910K395-9143K305/). I also designed a low-profile DIN mount which uses a pull plunger (https://www.mcmaster.com/8482A28/) or a 10-32 bolt.
