608ZZ Bearing Hanging Filament Spool Mount

prusaprinters

<p>Instead of using a 3D-printed arm for the spool, I decided to create a holder with a 6 inch bolt.</p><p>I designed this hanging spool mount to go under my workbench with my printers. I had lots of bearing leftover from the fidget spinner craze and decided to put them to use. Filament comes off the roll nice and smooth.</p><p><strong>Required Components:</strong><br>1 x 5/16 in.-18 tpi Zinc-Plated Hex Nut (25-Piece per Bag) - (Homedepot) - (<a href="https://is.gd/33W8Yd">https://is.gd/33W8Yd</a>)<br>1 x 5/16 in.
