Needed a storage box for a small electrical meter that came in a card board box, had good foam but wanted something better than the cardboard. I recently had printed the A1 mini tool box and really liked how the latch worked. So I imported the 3mf files of into Fusion and just cut in the middle in the x and z axis to make it wider and taller to just barely squeeze in the foam. Also made the holes for the pins around 4 mm and modeled pins to match that should press fit into the smaller hole towards the middle to avoid needing to buy special screws. Printed these in CF PLA for potential abrasion resistance but probably could be just about anything.

I do recommend turning off Ironing on any PLA + though as it just makes it look rough on my A1 Mini. Though PLA Matte looks amazing when ironed. Have included the Fusion 360 file to allow easy modding. If you right click on the model name on the list in Fusion you can easily export as STEP and pull straight into Bambu Studio or Orca Slicer.
