Bearing Spool Holder with Adjustable Platform

prusaprinters

<p>The spool holders that use bearings seem the most robust of all spool holders to me, but I've grown tired of knocking them over accidentally when I change filament. This platform helps keep them stable. It is adjustable to most common spool sizes for 1.75mm filament.</p><p>You may not need the 3/8" #4 wood screws that keep the bearing holders together, because the bearings should fit quite snugly. You will need 4 common skate wheel bearings for each spool holder set. You may be able to print your own:</p><p><a href="https://www.thingiverse.com/thing:3002837">https://www.thingiverse.com/thing:3002837</a></p><p>I normally print all parts at .12-.18mm. Smaller parts should be printed at highest quality (.1-.12mm). Supports should only be needed for the two inner spacer shelves of the platform.</p><p>The following quantities are needed for a single spool holder set:</p><p>Bearing_Holder_half - 4</p><p>platform - 1</p><p>support - 2</p><p>small nut and bolt - 2</p><h3>Print Settings</h3><p><strong>Printer Brand:</strong></p><p>FlashForge</p><p><strong>Printer:&nbsp;</strong></p><p>Creator Pro</p><p><strong>Rafts:</strong></p><p>No</p><p><strong>Supports:&nbsp;</strong></p><p>Yes</p><p><strong>Resolution:</strong></p><p>.12-.18mm.

My first try for the printable bearing was abject failure, so I guess I have a printer fine tuning project ahead of me. Luckily those 608 bearings have pretty well flooded the market (I always have a few spares on hand for my RipStik wheels).&nbsp;</p><p>Remixed from Thingiverse Thing: 2791247 (<a href="https://www.thingiverse.com/thing:2791247">Universal Tabletop Filament Spool Holder by Xtrudor</a>)</p><p>How I Designed This ===================</p><p><strong>Lots of boolean subtraction</strong></p><p>I used Cheetah 3D and boolean subtraction to get the supports (rectangular prism with trimmed corners and a hole) just right.</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>Category: 3D Printer Accessories</p>
