You could even scale the XY to fit an old Brutus shaft too. or let me know and ill update a model.

- I have only tested these two materials but I can imagine just about any material will be fine. It's only under compressive load for the most part.

Ever had a ball smash your valve off and wished you had those nice roger valve savers??  

Sick of the duct tape and zip tie look?

this will probably stop your valve from getting knocked off and look cool doing it. 

NEW: 
Presta V2 valve saver 
Schrader V1 valve saver

It's mostly friction fit. so no extra valve stem nuts are needed to hold it in place.
you could scale up the Z-axis if you want to make it taller + stronger... but heavier.

enjoy and have fun - print some pretty colorful ones and show how it looks on your bike! 

Printer:
Any

Material:
Any - I've used PC, Nylon, Nylon12, PETG, PET, and PLA so far. all work fine. 

Rafts:
No

Supports:
No

Resolution:
0.1mm ~0.3mm
anything is fine. 

Infill:
0

WALLS:
8

Notes:
this print is designed to be all walls and no infill. You can play with this if you want but I'm using all walls for strength.
