Ram mount with ball socket for 24.5mm ball joint on 1 end and 17.2mm ball joint on the other so it would clamp onto a phone holder i had lying around for my retired dad who wanted to use his motorcycle GPS in the car.
Also printed the backplate with the collar design so he could.
Changes from the original:
Set “long sweep” to 0 to maximize grip around the balls (needs manual changing in the script file)
