Mechanical Laser Show No-Support Version

prusaprinters

<p>Edit: Both X and Y Cams updated for better tolerance.</p> <p>Edit2: Realized I didn't add a change to the base I had intended. Notches to allow the snap-together crank handle to move freely around.</p> <p>My slicer doesn't do supports and I hate having to clean up after them anyway. So with a bit of creative re-engineering I made everything support-free friendly. One extra advantage is that the separation of the gears and cams means less printing time.</p> <p>Print one of everything plus one extra Bolt.stl (I actually just used 1/4" socket head machine screws.)</p> <p>On the bottom of the Cam(s) pull the extra ring of material free from around the hole.</p> <p>The X and Y gears should fit into the gear-shaped holes on the bottoms of the cams. Your tolerances may vary.</p> <p>Thanks to AdditiveTech for an amazing design!</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>Dremel Idea Builder</p> <p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div> <p><strong>Supports:</strong></p> <p>No</p> <p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>.2</p></div> <p><strong>Infill:</strong></p> <p>15%</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>Worked in PET-G for this project. Does OK (not great) at 230° which is my printers max temp.<br/> Reprinted X Cams in PLA and it bridged a bit better. <h3>How I Designed This</h3> <p>Used Tinkercad to scale and add/subtract parts.</p> </p></div></p></p> Category: Mechanical Toys
