Compact Folding Backpack Hanger v2.0

prusaprinters

<h3>Notes</h3><p>Changes from V1.0 (2019):</p><ul><li>New single-piece "carabiner" design for attaching to backpack strap</li><li>New hook design that reduces stress at the corner of the hook while keeping the same right-angle hook geometry</li><li>Made parts slightly smaller overall and significantly reduced material usage with only a minor decrease in strength</li></ul><p>When printed in PETG according to the instructions, I would recommend using this hanger to hold no more than 8kg (17.5lb). Based on FEA simulations and physical testing, the actual yield strength will be several times that.</p><p>This will hang from the top of a door, a hole in &lt;20mm thick material, or a similar object without any modification, but adding some nonslip material such as thin neoprene foam tape to the tip of the hook allows it to hang off a flat surface such as the edge of a table as shown below.</p><h3>Printing</h3><p>Print with 100% infill and at least 3mm thick perimeters in PETG, PC, PA, or any tough and slightly flexible material. 21c-p2 hook.stl must be printed on its side with supports enabled.</p><h3>Assembly</h3><p>Assemble the clip body and hanging hook as shown in the pictures and screw them together with an M5x16mm screw and an M5 nut, preferably a Nylok nut. Insert the strap of your bag through the loop in the hanger.</p>
