TUSH2-Style Spool Holder for Mk3S

prusaprinters

<p>The MK3S's stock spool holder works actually really well. Yet, I like <a href="https://www.thingiverse.com/thing:2853619">spongybob1958's TUSH2 design</a> and use this kind of spool holder with all my other printers, so I remixed it for the MK3S. In reality, it's more of a reimplementation in Fusion 360, with the adapter to attach it to the top bar taken from <a href="https://www.prusaprinters.org/prints/30022-filament-guide-for-mk3s">bbrendon's filament guide</a>.</p><p>The filament rolls very easily off these holders due to the bearings, and they adapt easily to spools of various widths.</p><p>The spool holders are compatible with <a href="https://www.prusaprinters.org/prints/22218-spool-holder-arms-for-tush2">my spool holder arms</a>, to keep the spools from being pulled off when there's not much filament left on the spool.</p><h3>Print instructions</h3><p>Prints without supports. I include gcode for PETG, 30% infill, 0.3 mm resolution but PLA is fine too.</p><p>To assemble, you'll need four standard 608 bearings, eg., <a href="https://www.amazon.com/gp/product/B07R7PR72H">https://www.amazon.com/gp/product/B07R7PR72H</a> and print a copy each of left-inside and left-outside, and right-inside and right-outside, that is, four parts. The outside parts have a raised guide to keep the spool from coming off the side.</p><p>In the gcode files, inside and outside parts are already combined into LEFT and RIGHT respectively.</p><p>Parts and bearings are pressure fits but if you want to secure it even more, the TUSH2 design can accommodate an M3 nut and an M3 x 12 bolt to hold it together.</p><p><strong>If you like what I'm doing…</strong><br/><strong> </strong><br/>…consider <a href="https://www.buymeacoffee.com/mix579">buying me a coffee</a>.<br/><br/><img alt="orange_img.webp" src="https://media.prusaprinters.org/media/prints/35053/rich_content/1a370a7b-cbf9-43fd-927e-979a843d803f/image.png#%7B%22uuid%22%3A%223d10f028-4c6b-406d-8294-7dac5c380665%22%2C%22w%22%3A170%2C%22h%22%3A37%7D"/><br/> </p>
