Silent wheels for the Prusa IKEA Lack Enclosure Spool Holder

prusaprinters

<p>After having finished the Prusa Lack enclosure from <a href="https://www.prusaprinters.org/cheap-simple-3d-printer-enclosure/">https://www.prusaprinters.org/cheap-simple-3d-printer-enclosure/</a> (things on <a href="https://www.thingiverse.com/thing:2864118">https://www.thingiverse.com/thing:2864118</a>) I printed the adjustable spool holder from <a href="https://www.thingiverse.com/thing:2867521">https://www.thingiverse.com/thing:2867521</a> which is a really clever idea for the lack enclosure.<br/> But the noise of the spools scratching on the non spinning wheels was a bit annoying. (see video - the original wheel isn't moving)<br/> So I replaced the axles and the wheel by using a ball bearing (8x22x7) with a printed tread and a matching two-part axle.<br/> It fits perfectly into the holder and is really silent.</p> <p>The treads of the wheels are 9mm wide and have a small lip to center the ball bearing.<br/> just slide in a bearing (usually no need to glue it - but depends on your dimensional accuracy), insert a square nut in the axle part, insert both axle parts in the bearing and screw it together.<br/> maybe consider to sand the tread to make it smooth</p> <p>Happy silent printing :-)</p> <p>I used a M3x20 screw with a M3 square nut to assemble the axle.</p> Category: 3D Printer Accessories
