1541 Ultimate Case "The Box"

thingiverse

For those needing a 3D printable case, here's one designed for U1 with an upcoming Ethernet version. A 40% fill and 0.6 mm wall thickness in PLA should suffice. Optional feet are available, but the case provides adequate cartridge support. The PCB measures 68 by 100 mm, so non-matching sizes may cause issues. Assemble with 3 mm wood screws on the bottom and 2 mm on the sides; some tightness might be expected depending on your printer and settings.
