Description

Update: Added a liner file. Print this in TPU and attach to the underside. After using these for 3 years, the porosity of PLA allowed it to discolor. The TPU barrier prevents that. You can still print just a cap and it'll work of course. I've Remixed "Subaru WRX Washer Cap" to add different text for the 2 reservoirs on my '95 STI. I did not make the "STI" logo, it was taken from http://www.thingiverse.com/thing:1330474. The text has gaps between the walls for me in Cura but I just bridged that with paint.
