Half-sized Breadboard Travel Box

Designed to hold header-mounted microcontroller boards (e.g. pico, teensy) and a small amount of peripherals/wiring/LED, so that you can chuck it in your bag for development work when travelling/at a conference/generally somewhere you have a computer and some spare time!

The base snaps shut with embedded magnets, and there is a label slot for Pred Parametric Label-style labels. If you are able to set up a python environment, these can be generated by e.g. my label generator package, but using the Pred blank-label supplies with that model should be easy enough to add in any CAD system.

STL/STEP design should comfortably fit around a 82x55mm breadboard, and magnet holes for four sets of two 6x2 magnets stacked - I found I needed two of my 6x2 magnets in order to get a strong snap.

There are minimal test prints for the breadboard fit, and the print-in-place hinges, if you want to test sizes before committing to the full print. The f3d file included has parametric variables to control breadboard size and the magnet size/embedded depth.

Printing

• Printing in PLA is fine, unless you want specifically sturdier. I've had PLA ones rattling round in my backpack for a while and they've been okay. Printing materials less good at overhangs may need the label slot to be supported.
• Set a print pause on the layer that covers over the magnets so that you can insert them
• Make sure you put the magnets in the top lip the opposite way to the bottom magnets!
• 3 wall loops
• 0.2 mm layers are fine
• The print-in-place hinges may need a little force to loosen them the first time. If you are worried about them, there is a test-print STL which prints a single hinge on it's own.
