3d model and stl for mounting the waveshare RP2040-LCD-1.28 in the MSA Millennium voice amplifier port. Has a separate compartment for a battery. Uses 3 M2 heatset inserts and M2x12 countersunk screws to assemble. Use an o-ring to get a good seal with the mask's voice amplifier port.
basic version with the vpu thread now available. I've merged the parts in the .3mf, and included the modified mesh in the f3d. VPU Thread adapted from https://cults3d.com/en/3d-model/various/gas-mask-vpu-cover-msa-compatible
basic version uses m2x4 heat set inserts and m2x20 set screws. You may need to press them in with a soldering iron due to tolerances, but after a few runs through should seat just fine.
