This is my final strap version for Oculus Go. Realy most comfortabe straps for GO i have tested. I have similar design for oculus quest 2 btw. Parts are printed on FDM from PET-G, but nearly any type of material is usable. Some parts like replacement for audio channels/strap holders were printed in SLA/DLP printer from grey basic material. I have originally used 2 types of chinese straps for oculus quest 2, dismantled it and combined together. Ali version of Halo type strap was useles so i used at last head bridge part. In reality you need just one strap and halo frontal part can be printed easilly by FDM. As external headphones i have used cheap replacement parts for koss porta pro from ALI.
