This is a wheel-nut / lug-nut cover for a Vauxhall / Opel Corsa 17mm.

I tried different materials but found ASA gave the best result, but I also got good results with PETG. PLA didn't seem to have the flexibility to fit without being either too loose, or cracking when fitted.

Printed on my P1S in a little over 2 hours.

There are 13 covers, which are 3 per wheel plus a spare, but I suggest printing one and rescaling in Bambu Studio to get the fit just right before printing all 13.
