Iron pipe bushings

prusaprinters

<p>I designed these bushings to allow a 1" iron gas pipe to fit inside a 1 1/2" iron pipe. It is being used to replace the flimsy tubing that came with my swing desk from <a href="https://www.amazon.com?linkCode=ll2&amp;tag=thingiverse09-20&amp;linkId=e4759bff1fa9a55a0f897d801ce2d765&amp;language=en_US&amp;ref_=as_li_ss_tl">Amazon</a> which failed in multiple different ways quickly. By using the iron gas pipe, the desk is extremely stable now.</p> <p>The lower bushing also provides a 6cm lift from the bottom for the inner pipe.</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>Biqu B1</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>0.2 mm / layer</p></div> <p><strong>Infill:</strong></p> <p>100%</p> <p><strong>Filament:</strong></p> Overture PLA <p>Black</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>Could probably use less infill on the lower bushing, but I made it as a solid piece which has worked really well. With 100% infill this took my machine just shy of 18 hrs to complete.</p></div> Post-Printing ============= <p>After printing, you will need to sand the outer layers of the bushings to get a good fit. The iron pipe I used had a ridge that I also had to remove most of to get the bushings to fit well. After a little sanding though everything fits as it should and the inner pipe does not move side to side in the larger pipe.</p> <p>The plug is meant to be used in the top bushing. I did not "predrill" the bushing in Fusion as I wanted to make sure it lined up with the screw hole I drilled in my pipe. After printing and fitting the bushing, I taped the bushing in place to make sure it wouldn't move. Then I drilled my hole for my 3/8-16 thumbscrew. I removed the bushing and tapped the hole in the iron pipe. The hole in the bushing I redrilled out to 1/2" as that was the largest drill I had. I then filed both the plug and hole until I achieved a good fit. The plug allows me to apply pressure to the inner pipe without metal on metal contact.</p> </p></p> Category: 3D Printing
