Craftsman Garage Door Opener Gear

prusaprinters

<p>This was modeled from a 3/4 HP Craftsman Garage Door Opener (P/N 41A5483-14). It replaced the worn helical gear which drives the mechanical Door Open/Door Closed sensor in the garage door opener.</p><p>When I measured the original gear it measured 0.600" OD and no longer properly meshed with the mechanical sensor gear. There are two versions below: 0.630" OD (+5%) and 0.660" OD (+10%). &nbsp;STEP and STL files are provided for both.&nbsp;</p><p>&nbsp;</p><p>The part was printed as follows:</p><p>Material: PETG</p><p>Layer Height: 0.20 mm</p><p>Supports: None</p><p>Build Plate Adhesion: Skirt</p><p>&nbsp;</p><p>Post Processing:</p><p>The ID should be 0.285". If the ID prints too small, it will need drilled with a ‘L’ &nbsp;bit. I used channellocks to hold the square end of the part and keep the taps from deflecting while drilling through. If the part needs drilled, go slow as plastic tends to catch the flutes in the bit.</p>
