After searching for a knuckle strap for the Quest 3 controllers I couldn't find any to buy or print which i liked. So i decided to modify the model of SSpt to get a feeling like with the strap on the Valve Index Knuckle controllers which I loved. The result of my design feels for me very similar to the Valve Index Controllers (Valve Knuckles).

Instructions:

• Print all parts in the uploaded orientation in 0,15 mm layer height.
• Lid parts should be printed with standard support
• Strap should be printed with Arachne Perimeter
• Cord holder 
  • can be printed without support, but better print it with support here
  • print with 100 % infill
• For connecting the Strap to the cord holder, use elastic cord of 3 mm diameter (e.g. [https://www.amazon.de/dp/B07FK152QV?ref=ppx_yo2ov_dt_b_product_details&th=1](https://www.amazon.de/dp/B07FK152QV?ref=ppx_yo2ov_dt_b_product_details&th=1)) - approximately 2 x 240 mm long
• For connecting the strap to the lid, use an inelastic cord (feels better than elastic to me) - approximately 2 x 65 mm
• Only tested in PLA (especially for the cord holder, PLA has better springiness than PETG)
• For more comfort, glue some kind of textile on the bottom of the straps with double sided tape - I used softshell textile (thickness  ~ 2 mm) I found in the closet of my girlfriend - feels super nice, any other textile should also work
