Servo Arm for Auto Level

thingiverse

Thanks to Bryan for the awesome source code! Check out the original source files from Bryan - it's a total breeze. You'll also find other cool code in there for SG/MG90 servos and related goodies, which should help you figure out those dimensions in OpenSCAD. This remix is specifically designed for the Servo Arm, and I've used it on my trusty Folger Tech 2020 i3 Prusa. The Servo Arm has been made to fit a microswitch with 2mm mounting holes spaced neatly at 6mm apart. If you need different spacing, just head to the section labeled "Holder screwholes" and make those edits - easy peasy! You can check out some example switches on Amazon by searching for "microswitch." Make sure to choose one that doesn't have any "snap" in the description, or it won't trigger smoothly when dropped. You want a microswitch with next to no resistance so the carriage will unload neatly. On the very last line, change the ## symbol to whatever length you prefer - for instance, I've used 61mm (switch_arm(61);). And as a little extra tip, I moved the holes closer to the edge of the arm so there's enough overhang for the microswitch. I printed this with 30% infill - but honestly, it doesn't really matter that much! Just one more thing: be sure to get a switch without "snap" in its description; you want it to have hardly any resistance at all, or else the carriage will just unload instead of triggering when dropped. Print Settings Rafts: Don't even worry about it! Supports: Who cares? Resolution: Get this to .2mm for top-notch quality. Infill: Go with 30% - simple and effective!
