Use your existing Quest 3 strap on your Bigscreen Beyond to get maximum comfort! The mod is simple and snaps right in, you may want to add 2 cable ties per strap point just for insurance but the snap fit with PLA is perfect. Untested with BSB2, but it should work.

The files are ready to print and I have included .F3D and .STEP for those who wish to modify, happy printing and enjoy! Please print in PLA, PETG, ABS or ASA with 5 walls and 30% Gyroid infill for the best result. Supports are needed, paint them where necessary.
