Computrainer Rocker

prusaprinters

<p>My Computrainer Rocking design for indoor training. I've been doing a lot indoor riding on Zwift lately and my behind is starting to hurt with the longer rides (1hr+). So after seeing some minimalistic designs for other trainers, I decided to make one for mine. This is what I came up with using what I have.</p> <p>V1 was just the middle pivot and using the plastic feet to mount the dampers. Worked ok, but it had some movement, but worked for me.</p> <p>I added the damper mounts so that I can move the mounts inward more (I used the knurled knobs and the nut thread from akira3dp0's design; <a href="https://www.thingiverse.com/thing:1460364">https://www.thingiverse.com/thing:1460364</a>) Added the 20mm bolt as a convenience. I will be doing a ride later and post a video of it when I get a chance.</p> <p>I updated the damper mounts with V2 as the first one had the threads in the wrong direction. Removed the old one.</p> <p>Update - 22NOV2020</p> <p>I realized that I need to adjust the height of the damper mounts as the floor isn't level. So I added adjustable knobs so that it is leveled before I put dampers. Printing them out now and will add pictures when done.</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ender 3</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>Yes</p></div> <p><strong>Resolution:</strong></p> <p>0.32</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>25%</p></div> <p><strong>Filament:</strong> Generic PETG &amp; TPU Various</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>the Pivot and Damper Mounts were printed in PETG with a 25% infill.</p> The dampers were printed in TPU using 1 wall. It will be very stiff if you add more than 1 wall. You can vary the infill percentage to get you the amount of flex, but I ended up printing them with 12% infill with the gyroid pattern. Change them to your liking. <p>You could also pickup different damper material that you can use. I tried to make everything using my 3d printer as a challenge.</p> <p>I recommend printing the adjustable bolts for the damper mounts with a higher infill as it'll have to handle supporting your weight/movement. As an alternative, you could always use an M16 bolt for that, but the knurling nut (that I have modified) fits perfectly with the dampers that I have.</p> </div></p></p></p> Category: Sport & Outdoors
