This cupholder has a way better point of gravity for better functionality of the gyroscope. It should be mounted with common M5 screws and nuts, please use nuts with thread lock. There are also four space holders which should be mounted between the circles of the gyroscope.
V5: Rounded design, updated to a more common M5 screw, added pull utensil for pulling up the cup.
MidRingV2: Lower attachment which causes the ability to rotate over 50° (old Version 25°). So you don't need special mounts for the use on slant handles.
CupPlacer: Cup is held precisely fixed in the middle of the CupHolder. (If there is demand, I could design an appropriate design for you guys)
