Gimbal Taper Cup Holder

Gimbal Taper Cup Holder – GTCH
Robust, self-leveling, specifically designed for 3D printing, tested and refined over several years.

May last for years of daily use, depending on materials,  construction, and any impacts. 
Fits many common tumbler cups nicely.

Tool-less clamp fits bars 7/8” – 1-5/16” (22-33.5mm) diameter.

In addition to the robust plastic part designs, the GTCH uses common 608 cartridge ball bearings and other metal hardware. 

See page 4 of  CHA02D.pdf assembly drawing for parts list. 

However common, they these are not OTS parts at Maker Supply thus you may need to source your own.

Usage and cautionary notes:
o When bike commuting, I use the GTCH with my to-go cup, the lid is on, and it seals well. The to-go cup was selected to fit so the cup goes in most of the way and the lid is just above the top, it is stable, some taper to-go cups especially the thicker insulated ones are not stable.  
o However even with a stable and good fitting cup, I put my finger on top the cup when going over bumps to minimize the movement and keep in place as bumps or jumps may cause your beverage to bounce out. 
o Some movements may cause yoke to rotate around then beverage may fall out.  One may put an elastic band around yoke and anchor to clamp, which can limit rotation and still allow to self balance. Also one may put an elastic band over the beverage cup and around the yoke to help secure it, ...but then it's not so quick as to get a sip and go whilst stopped at a traffic light imho. 
o Depending on weight of cup and beverage the GTCH may rotate down on the bar with large bumps or other forces to help avoid overload conditions. 
o Over tightening clamp may cause failure.
o Keep fingers etc. out of area in front of center yoke attachment bolt to avoid pinch from cup holder bottom edge rotating by (not likely but it can bite).
o Use at your own risk.
o Not a toy.
Not intended for children.
Enjoy!
