Spool adapters for 22mm bearings

prusaprinters

<p>So first let me tell you that using bearings can cause filament spools turning to easily. This can also lead to problems but for me this has always worked out quite well. Probably because the spools have some resistance in rubbing against the wood from my spool holder.</p><p>I like to print one of these adapters for every new color I get if I don't have one to reuse. Since this uses quite a lot of bearings you should either get really cheap ones or have access to well used ones.</p><p>I might add additional adapters here if I need to design them.</p><h4>Print instructions</h4><p>All adapters should be printed with supports. I prefer to use the paint on supports so that the letters are clearly readable.</p><p>For the master spool there is a padded version so the bolts don't have clearing problems if the filament roll slides against the holder.</p>
