Storage plug for Shimano brake caliper or lever with M8x0.75 thread

prusaprinters

Simple plug to install in a Shimano brake caliper or brake lever with an M8x0.75 thread, usually what you'll see at the end of a brake hose that is installed with a barb and an olive.Good for storing the brake lever or caliper when there's still fluid in it and you don't want to drain it and don't want it to leak and make a mess. Probably won't hold pressure so if you inadvertently pump the brake lever, it'll probably still leak.Printing instructionsThe M8x0.75 thread is quite fine so I recommend a layer height lower than 0.2mm, I'd got with 0.1 for the threaded portion. The rest of it can be whatever layer height, so use a Height Range Modifier so you don't waste detail on the grip. Can be printed in any material, you might want to bump it up to 3 or more shells for a little bit more strength, but honestly this shouldn't be holding all that much tension so that might not be necessary. If it breaks in the caliper or lever due to poor layer adhesion, having some infill will let you jam in a small flat blade screwdriver to hopefully turn it out, so I'd make sure your printer is pretty well tuned to avoid that.
