Mazama M!GO Bottle Cap Tether

A cap cover + tether for the Mazama x Miranda Goes Outside M!GO Bottle since there's no official one yet.

Fully removable, but you could glue the cover onto the cap if you wanted. It fits perfectly over the cap and TPU has enough flex and grip to keep it there. You could try scaling a fraction of a percent down if you want a really tight fit. The ridges are modeled into the cap so that it's able to grip the slots in the cap for screwing and unscrewing without slipping. The tether is pretty tough to slip all the way onto the bottle because I don't like them to spin freely, but it's still able to be rotated easily with intent. 

Printed in TPU for the tether to be flexible and cap to fit snug and rubbery, but I suppose the cap cover could be made out of other materials. Both colors are from Overture, the neon yellow is high speed TPU which is slightly stiffer, and the digital blue is regular TPU, and just a few shades darker than the blue on the bottle. The tether is better in the softer regular TPU, and the cap better in high speed TPU which has a little less friction for rotating within the tether ring.

Designed with flat surfaces for printing on “designer” plates, I used a holographic plate and octogram spiral for a fun effect on the top of the cap and outside of the tether. You could also emboss some text if you wanted.

Tether v1.4 - Added strain relief notch at the connection to the cap ring to reduce tension on the cap ring, but it could conversely also be a potential weak point.
