This design has been updated with AUX port. You can find this new design at: https://www.thingiverse.com/thing:5767765 My PC has USB 3.0 ports only from its back (yes, it is already getting mature). I wanted to bring some of these to my desk to avoid having to ‘deep dive’ every time I need to connect something reasonably fast way. I have bought this cable and designed under-desk holder for it: PremiumCord USB 3.0 Super-speed 5Gbps A-Ahttps://www.alza.cz/premiumcord-prodluzovaci-kabel-usb-3-0-super-speed-5gbps-a-a-mf-9pin-2m-bila-d6696333.htm I think the design might work for some other brands as well as it is quite common shape for this type of wire. You should use 2 pcs. of 3mm screws to fix it to the table - whichever length works for you, I have used 16mm. Easy to print, but you need to position the objects properly to the printing bed. Consult the picture for object orientation on the bed. I have used 0.6mm nozzle, orange PETG filament, 55% infill and supports. Happy printing :o]
If I could I’d give another upvote for including the aux jack option.
