Don't have a 3D Printer? My models print great with These Printers (affiliate)
Spill Proof?
This coaster transforms into a spill-proof coffee carrier! This design is spill proof, thanks to physics! The center of the handle is directly over the center of the mug, much makes it spill-proof thanks to centrifugal force! The stretchy hair tie also protects your mug from bouncing!
This design took over 50 iterations to get it working perfectly. The articulating hinges, and gravity lock mechanism were particularly tricky to get working, but its finally ready!
How does it work? Print in place hinges allow the bark to unroll. And a 90 degree hinge lets the handle rotate up and lock into place so you can carry your drinks! It locks via a special tilt-lock mechanism that keeps the base from tipping over when a mug is on it.
Magnets (optional) Zap the handle onto the coaster so you can move it around without the handle coming loose.
There is a spot to place a piece of cork in the center, for a super finished / polished feel.
