Single Sided Under-cabnet Paper Towel Holder

prusaprinters

<p>This is an under cabinet mounted paper towel holder. The design is comprised of three printed parts (no supports) and a center metal tube. The top and main arm sections are joined with CA glue and a tight fit between parts. The holder is designed to mount to the underside of a kitchen cabinet with the appropriate length wood screws (4x) but it has enough surface area such that Command strips or VHB tape would probably work as well.</p><p>&nbsp;</p><p>This holder was designed with a single arm and end cap to make replacing the paper towel roll easier than some other designs. A metal tube was used in place of a fully printed part for strength and to avoid issues with printing a long cylinder. The STL file posted here is setup for a 7/16” OD aluminum tube that I had lying around but the Fusion file is parametric with custom user parameters for the center tube ID and OD so generating new STLs for whatever diameter round tubing you have lying around is quite easy. The ‘end cap’ and ‘arm mount’ pieces are a good friction fit on the center tube on my setup and glue wasn't necessary.</p><p>&nbsp;</p><p>Printing Parameters: Prusa MK3S+</p><ul><li>Standard PrusaSlicer settings/temps except where noted</li><li>.4 MM Nozzle</li><li>HATCHBOX Magic Stone PLA in Granite</li><li>.20 MM Layer Height - PrusaSlicer ‘Quality’ setting</li><li>30% Infill for arm and top mount, end cap printed at 15%</li><li>Prusa smooth PEI sheet</li><li>No supports required</li><li>Print Time on my setup: &nbsp;7H+4H+.5H so approx. 11.5Hrs total</li></ul>
