Aluminum Extrusion Foot

prusaprinters

<p>Want your aluminum extrusion structure to slide better, protect the floor below, or sit more level? These feet can be printed from TPU to provide a more compliant, soft bottom. I designed these for my desk and new 3d printer workbench, constructed of 2020 and 3030 series extrusions.</p><p>There's also a hole for an M5 screw if you want to fasten it to the extrusion (although it does stay on pretty well without a screw too)</p><p>There are different feet for 2020 and 3030 series extrusions</p><p>Recommended Print Settings:</p><ul><li>Material: TPU (I just used some old Inland TPU I had)</li><li>Temperature: 225, 60 (may vary depending on brand)</li><li>Top/Bottom Layers: 4</li><li>Walls: 4</li><li>Infill: 30%, lines (you can adjust this to make them stiffer or squishier)</li><li>Print Speed: 10-15 mm/s*</li></ul><p>*slow speed is very important to having TPU print well because it is squishy/stretchy!</p>
