Brake reservoir lid for Shimano M355

prusaprinters

<p>If your brake reservoirs crumple, you may be using an automotive brake fluid (dot 5.1) in your brakes. This will destroy them and many plastic things along the way. I learned the hard way. For Shimano nrakes, use mineral oil only.</p><p>Hi, my brake fluid reservoir covers disintegrated, so I spent a day making a 3d printed ones. The M355 lid already on Thingyverse leaked as its made for injection molding, not 3d printing. These should not leak, but I haven't tested them extensively (yet). Maybe they do just a little bit. I'd love to hear from you and improve them with your feedback.</p><p>The cad files are a mess as these are a traced photo + the stl file from here <a href="https://www.thingiverse.com/thing:3484736">https://www.thingiverse.com/thing:3484736</a> for the seal and screw holes and completely freehand for the rest, so I'm not sharing them here. You can still dig them up on Onshape if you really want.</p><p>It seems like the original covers are made out of a plastic material that weakens rapidly when exposed to the brake fluid. So their kryptonite is literally the thing they are tasked with containing. (Yes there is a rubber thing in-between)</p><p>If you don't like the text, it's pretty easy to get rid of, or just ask for a version without one,</p><p>Hope this helps you ride safely again :)</p><h3>Print Settings</h3><p><strong>Printer:</strong></p><p>RebelX</p><p>&nbsp;</p><p><strong>Rafts:&nbsp;</strong></p><p>No</p><p><strong>Supports:</strong></p><p>&nbsp;</p><p>Yes</p><p>&nbsp;</p><p><strong>Resolution:&nbsp;</strong></p><p>0.2 mm</p><p><strong>Infill:</strong></p><p>&nbsp;</p><p>I did 30 and 70, no idea what's best</p><p><strong>Filament:</strong> Prusament PETG or tougher, no PLA for sure Green&nbsp;<br>&nbsp;</p><p><strong>Notes:&nbsp;</strong></p><p>Print with the text on the bed</p><h3>Post-Printing</h3><p>You may need to enlarge the reservoir fill port hole just a little. Also careful when installing this. I stripped the thread in one of the holes a little. If it does not go on there, enlarge the holes, don't force it with screws. Aluminum is too soft for that.</p><p>&nbsp;</p><p>&nbsp;</p><p>Category: Sport &amp; Outdoors</p>
