I have spent so much time trying to get my brakes to be good enough to pass a mechanical inspection so I have been 3D printing caps, connectors and plugs to make things easier…. All with M10 x 1.25 threads.
I have also found on my journey that brake bleeding kits either do not come with 1.25 thread pitch connectors or if they only give you one…
So the picture below shows….
Short screw-in plugs for the MC to prevent leakage of a newly bled MC whilst struggling to connect all the hard lines.
Bleeder attachments for the MC if in the event you want to pump the piston with all three ports venting together.
End caps for hard line brake unions which are useful to stop fluid leakage disconnected. I have also used these to isolate individual brake calipers during problem investigations. The end cap threaded hole is conical at the end to make a good seal with a bubble flare.
MC reservoir caps.
I also seem to be collecting and re-building master cylinders and calipers. These plugs and caps are handy to block off ports, keeping fluid in and moisture out during storage.
If nothing else, then this at least shows that you can 3D print perfectly good, well fitting threads.
Cheers

PS One can of course make plugs from cut down M10 x 1.25 hex head bolts and also make mini brake lines using spare brake unions for MC bleeding but where is the fun in that if you have a 3D printer !!
