Cap for brake fluid bleeder jar

Cap of my brake fluid bleeder jar was damaged. The top of the cap was cracked and I tried to glue it without success. As I cannot find just the cap on the market, I decided to design and 3D print one

Design done using Fusion 360 from original cap and adapted to 3D printing. Mainly the top of the cap which is flat and not curved as original one

I printed 1st a prototype with low cost Recycled PLA to check that all is correct and mainly the thread of he cap. Is used ISO thread 50mm diam x 4mm pitch and modify the inner faces of the threads to have more space between bottle and cap

Printed the definitive one in Prusament PETG using 0.20mm layer height and standard PrusaSlicer parameters

No support needed if you print it upside down

On top of .stl and .3mf files I uploaded Fusion 360 .f3d one so you can modify the design and adapt it to your needs

As usual, feedback and comments (and for sure "likes") will be always welcome. Feel free to post nice pictures of your makes

Enjoy
