Screw Gauge for M3 & M4

prusaprinters

<p>When I'm prototyping I always seem end up with random screws that I didn't need to use or that came out of something I disassembled. I'm not great at eyeballing lengths, so I made this little gauge for M3/M4 screws. Just drop the screw into the holes to see where it bottoms out. Then put the screw into the right container. Actually, I often just hold the screw up to the outside rather than putting it into the hole.</p><p>It's not really an essential tool, but I've found it useful. I included a Fusion 360 model in case anyone would like to make modifications.</p><h3>Print Settings</h3><ul><li><strong>Printer: </strong>CR10S PRO</li><li><strong>Rafts: N</strong>o</li><li><strong>Supports: </strong>No</li><li><strong>Resolution: </strong>0.2mm</li><li><strong>Infill: </strong>15% (not critical)</li><li><strong>Filament: HATCHBOX PLA</strong></li></ul><h3>How I Designed This</h3><p>Super simple design in Fusion 360. It's a 3.5mm circle, a 4.5mm circle, and a rectangle in a rectangular pattern. Each rectangle is extruded to an appropriate length and that length is then debossed into the face. You can see the text in the attached pictures.</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p>
