Info:

• another bike valve cap model
• I took skull base from @ncsandor (thanks for design!) and remodelled with some terrifying factors and adjusted so it match valve cap and is still printable without supports

Not for presta valve! 

Print instructions:

• 0.4mm nozzle works good for me (for my MTB), I have already scaled original to best fit, so just print this at 100% scale or adjust slightly.
• 3mf file contains variable layer height, bottom part must be 0.05 layer height so the thread works well
• no supports

Note that on image is just a render, not actual print photo (I am out of printer atm).
