HDZero Goggle faceplates with mounting for custom prescription lenses

Update 01-18-23 Wide faceplate added!

Update 01-17-23 I rebuilt the model from the ground up and improved it further. Added the step file for those who wish to make changes. Coming soon: Wide Faceplate version!

Update 01-16-23 I replaced the models with improved versions, cleaning up a few defects in the stl.

These are the narrow and wide faceplates for the hdzero goggles, modified to allow the use of fatshark diopter shaped prescription lenses such as what RHO-Lens sells. Order lenses for the fatshark HDO2 (or any fatshark diopter shaped lens) to fit this design. I've also heard lenses made for the Orcas work as well.

With this mod, and my prescription for astigmatism, I am able to see and focus on both screens in their entirety. Also with the stock foam, my eyelashes do not touch the lenses. The IPD is set by RHO-Lens when you order, and the mod installs the lenses so that IPD will be recreated correctly in the goggle, based on the data you gave to RHO-Lens. The modded faceplates do not interfere with the IPD or focus adjustments in the goggle in any way. Finally the custom lenses may be installed or removed (so others can use your goggle) without removing the faceplate from the goggle.

The best way to print them is “angled” and the STL's I supply are preset in the best orientation. See the pictures showing the finished slicing of the model in the angled position. Use a raft (reduce part separation to 0.06 from the typical 0.14 and increase raft size as needed to capture all of the model and supports). Auto generate supports (from build platform only) with overhang angle set to 45 degrees and 1mm grid. Then go around and check obvious places (such as the lens holders) and add (or remove) as needed and also remove any single support pillars (that will likely fail anyway). I use 30% course and 4 layers of 70% fine support at the top only. Support pattern set to aligned and pattern rotation set to 45 degrees. Important, be sure to set support horizontal offset to 0! Having any offset other than zero, when supporting curved surfaces, is a bad idea. 0.2mm layer height and 1 layer support separation at the top (remember we are supporting from build platform only so bottom separation can be 0). Use at least 3 perimeters. Best to use ABS or ASA but PLA will be fine just don't leave it in your car on a hot summer day. If using ABS or ASA use the part cooling fan starting at layer 300 (assuming .2mm layer height) at 40%. Do not use the cooling fan earlier in the model for ABS or ASA. For PLA or PETG use cooling fan as you would normally.

Not sure if a resin print will handle being clipped into the goggles (even the strong resins are weaker than most FDM plastics), although it would likely look fantastic. If someone tries it please let me know how it worked out in the comments.
