Cap for 45mm European auto brake fluid reservoir

thingiverse

This thing is a byproduct of another project of mine. I am making an adapter with a threaded cap in order to more easily pressure bleed the brakes on my Toyota Tacoma. Normally one would use a "universal" adapter thingy with chains and a rubber stopper that is a real kluge and PITA. The cap for the one I am working on is essentially this thing but it has a barb to connect up an air line for pressure bleeding... so it was trivial for me to make one without the barb in case anyone needs one. It should fit any standard Euro type brake reservoir with a threaded 45mm cap. Threads are 45mm x 3mm pitch. The second thing file is for a gasket you can print in TPU or other flex. But a piece of Viton rubber cut to fit would probably work better.
