Practical doorstop

<h3>Stop it!</h3> <p>Yes, I'm back with more bad puns and a useful print.</p> <p>This practical, easy-to-print design was something I threw together in Fusion 360. I didn't want a Hodor (sorry) or a solid doorstop. Instead, I wanted something that would squish a little, grip the carpet, and truly hold the door.</p> <p>Designed to be printed in a flexible material (semi-flex seems ideal), this doorstop has "teeth" on the bottom to grip carpet and "bumps" to grip the door in a ratcheting fashion. While this might work on a hardwood or other bare floor, eliminating the teeth might give better grip.</p> <p>Pushing the door against the doorstop will compress the doorstop a bit, allowing the ratcheting action to take place. In fact, when sufficiently compressed under the door, this doorstop will actually prevent the door from moving in either direction from a breeze - perfect for days when you can't predict how nature might toss about your doors when the windows are open.</p> <p>Is your printer unable to print flexible material? You certainly can try PLA, ABS, or some other material and try your luck. With a somewhat plush carpet, you might have luck. If you do, post your make and let me know!</p> <p>Check out the<em>strangely satisfying</em> video on YouTube: <a href="https://youtu.be/_sBXNNziRxc">https://youtu.be/\_sBXNNziRxc</a></p> <p>If you want to support me and get GREAT filament at the same time, please visit <a href="http://www.proto-pasta.com?aff=51">Proto-Pasta using my affiliate link</a> and get yourself some excellent HTPLA!</p> <h3>Print instructions</h3><h3>Category: Household Print Settings</h3> <p><strong>Printer:</strong> BobsCNC RP9 v2</p> <p><strong>Rafts:</strong> No</p> <p><strong>Supports:</strong> No</p> <p><strong>Resolution:</strong> 0.3mm</p> <p><strong>Infill:</strong> 50%</p> <p><strong>Notes:</strong></p> <p>I used TPU filament from FoxSmart - a semi-flex material. This works great at slow speeds even in a bowden setup (18-20mm seems to work just fine). Just make sure not to squish that first layer too much or you might have that filament herniate right out of your extruder.</p> <p>It's a long print (8 hours for the slow speeds I took to print the semi-flex) but the end product is quite effective!</p> <p>If you want to avoid stringing and wisps, use the settings in your slicer to avoid crossing boundaries. It might take a bit longer but it can result in a flawless print.</p>
