I redesigned this for an easier print and to attach the 'key' to the slide over casing. The 'Bracket Casing' slides over the Pimax brackets and then the 'key' tab is pushed in place. Hold the casing/metal in(towards center) then slide the matching DAS Plate in place and attach the DAS. There is some forward movement in the 'DAS Plates' but the DAS prevents the plates from moving, and can only be removed by taking the DAS off and angling the brackets inward. The plates are also pulled into a 'locking position while the Pimax is on and the strap is tightened.
You will also need a 'Top Adapter' from Drcube's DAS Adapter to complete the set.
This is a remix of DrCube's Pimax + Vive DAS Adapter(used DAS peg portion), but instead of removing the Pimax hinges, these pieces slide over the hinges and use the strap loop as a locking pin cutout.
I've noticed alot more L/R downloads than the 'key', don't forget to download the key.stl if you are using V2.
V2This was printed with the DAS post up which requires the cutout section for the Pimax hinge to be filled with support material, which requires more cleanup than what I've dealt with before. If someone tries a different orientation that works, please post a comment. The scale of the 'lock' piece may need to be adjusted as this was designed to fit snugly as you don't want this to fall out.
