I am 8k Backer / Lurker around 485s (not my exact value) and waiting eagerly for my Pimax emails and shipping confirmations…
I am also a Programmer, Designer and a Tinkerer… and impatient, liking taking a cracks at a problem, looking for solutions.
I had also previously designed a rudamentary Headgear mod for My Vive prior to waiting DAS (Deluxe Audio Strap) prices to dip.
Now I am in a similar situation where I want to use my DAS (the prices never dipped, thats 99 € just for the damn headgear and some slighly better than average audio, so I want to reuse it) on the Pimax, but
I dont want to glue or tape velcro onto the DAS, like shown with the “Frankenpimax” method that was show by @mixedrealityTV. Instead I like to make a more utiliterian solution which you can swap the same headgear between headsets, without having to mess around with cables much.
First Prototype Release, With full Assembly Instructions. Use at your own risk
Already have some progress regarding the mounting joinery for the DAS and have it figured out the dimensions and mounting methods to get them working just fine:
Now I just need the other measurements and I can basically create an adapter for the Pimax
Taking account printing directions and toughness, this should be atleast as tough as the connection point it self, with the right printer tolerances (0.1 mm layer height ±50μm dimension tolerance) and materials. In this case my recommended material is PETG (not PET), which is a very good material for the subject, this works well with friction based joineries, due
A. Flexes more than ABS as a softer plastic.
B. Its a weaker than ABS, but its stronger than (regular, non enchanced) PLA, so probably avoids damaging to the headset over prolonged use.
C. Its much simpler to print than ABS as its less toxic to print
Thanks to @UnholyBeardedOne I now have all the information to continue
Will use this thread as a log.
So to go forward with the project and have more accurate info I am looking for the following measurements
The diameter of the rod (blue), side (purple)+bottom(green) clearance room between the rod and the length of the rod (red) as shown on sebastian’s velcro mod video In this however, the diameter of the rod is the most important part as without it I cant make a snug fit, with the both clearances secondary, while the height of the rod would help with joint stability and give more surface area to play with .
The Dimensions of the inner Hole (purple red) and the outer hole (blue, green) of the top and the distance the hole is from the edge
Once Done and tested, will release the print files under CC Attribution Non-commercial license which you can send to a local 3d printing service for a few dozen bucks if you dont have a printer of your own.
This should also allow for modifications for other headsets from pimax, or others in the future. Ofcourse, the caveat for all would be “use at your own risk”
