Replacement Steelcase Leap caster wheel

prusaprinters

<p>Replaces a 75mm wheel on a stemless caster, for an older Steelcase Leap office chair.</p> <p>No idea how this will hold up over time, or which models it's compatible with, sorry!</p> <p>I increased several dimensions to reduce weak points, including the overall width of the wheel, so it will not match exactly (see picture).</p> <p>I'd recommend printing only the center spindle of this to test the fit before printing the whole thing. I increased the center hole size to compensate for shrinking holes in my print, that a better calibrated printer might not need.</p> <h3>Print instructions</h3><p>I printed this with the visible side up for appearance, and used supports around the outer ring underneath, letting the wider, flat portion bridge. Worked OK.</p> <p>Used lots of extra plastic (PETG here), by printing at 50% gyroid infill, with 3mm worth of external perimeters and top/bottom layers.</p> <p>I set the layer height settings in Slic3r to manually taper the layer height down to 0.04mm for the top layers.</p> <p>Print took around 9 hours</p>
