19/6/23: Modified base mount with a hole to optionally fit a second cable clip on the back. This allow to fix a set length of cable to always be available for movements, preventing for example the cable available to get too short by slipping behind the desk. Also added an extra short 19mm pin option.

I modified the mouse bungee with a few improvements. I thought the mount was unnecessarily big, so I made it smaller and use less unnecessary material, also to be less conspicuous. I changed the locking system to push pins to achieve a tighter fit with nearly no wobble (any wobble left comes from the ball bearings themselves and can't really be eliminated other than by adding a second set of bearings.) I also added a set of cable clips to accomodate for different diameters of mouse cables out there. ranges from 2.5 to 4mm diameters. Your printer might make these holes bigger on smaller so don't rely on the cable measurement too much. Easiest way would be to print them all and see which fits better, you'll want a nice snug fit. I also made two versions of the main pin, 28 and 38mm to allow you to choose how far you want to distance the whole assembly from your screen. I also made it so that the bearings are hidden. (picture uses an old version. you won't be able to see the bearing on the new ones.

Please note that by design all tolerances are fairly tight. There's no way to ensure parts made from all printer will always fit perfectly with each other. Sanding shouldn't be needed, but it might be.

While not necessary I suggest gluing the base mount and the pin together.
