Print-in-Place Hinged Box for 4x CR123A Batteries
Compact, one-handed operation storage box for 4 CR123A batteries (or CR123 or RCR123A or 16340) with an integrated hinge. Optimized for one handed use.

Materials needed:

2 x magnets (size 3 x 2.5 mm - those sold as 3x3 are usually this size), should press fit with a firm push (fusion 360 file provided where you can change magnet size slightly if needed) or just glue them otherwise.

Recommended Print Settings:

  • Nozzle: confirmed working with 0.4 and 0.25 nozzles (i have uploaded different files i have actually printed and have come out working smoothly)

  • the v 1.1 files have: holes for pushing the magnet back out with a pin, more material around the magnets

  • Layer Height: Smaller is better but works with 0.15

  • make sure seams don't interfere with hinge operation. use painted on seams in your slicer if necessary

  • Material: PLA or PETG

  • No brim needed

Recommended post-processing:

  • sanding of the bottom edges / deburring with deburring tool/knife - or avoid by using elephant foot compensation
