Description

So I misplaced the cap for coolant fluid on my Volkswagen Polo 1,4. I couldn't find any models that fitted so I made one. Hopefully someone else has use of it, enjoy! Printed mine in PLA and welded on a testcube when engineering. There's one version without handle if you want to print without support and glue/weld something on. Print at your own risk and use a filament that withstands the hot environment.
