Headphone Holder with Cable Management Spool Table Mount Version - with STEP file

thingiverse

This is a desk mount headphone holder with a ratcheting cable spool. The desk mount is remixed from philbarrenger's awesome "Monster Mouth Headphone Holder - Clampable" (https://www.thingiverse.com/thing:1657541), and the rest is a remix of my "Wall Mount Headphone Holder with Cable Management Spool - VERSION 2" (https://www.thingiverse.com/thing:4202518). This thing will require: * Two M4 nuts * Two M4x12mm flat head bolts (It should be possible to use round head bolts with the newer design) * One 608zz bearing, which can be salvaged from an old fidget spinner * One spring from a ball point pen * Two #8 flat head screws for wall mounting * Optionally a rubber band, to quiet the gears. I tried a normal rubber band which was relatively thick and also a rubber band from a bunch of asparagus which worked a bit better but also added some resistance to turning. * Glue to secure the Clip on the back of the Base once everything is working. I'm not your mom, but eye protection is required when assembling. To assemble: 1. First install the bearing on the reel. Using a second bearing to set the first bearing can help. 2. Then place the pen spring into the hole in the back of the base. 3. The sliding part will go in next, and capture one end of the spring. Ideally the spring action of the slider should be moderate and should not take much force to move it in the track. I'd say the pressure of the slider should be similar to the pressure of the cap on the pen the spring was removed from. If it does not move freely, remove the slider and try sanding the base and cleaning up the part. 4. Now the base would be mounted to desk mount using the M4 nuts and bolts. You could also add glue at this point. 5. Finally, install the reel by pushing the installed bearing onto the post of the base. Note that the post will be a tight fit and once on, it probably won't come off the post without breaking - but it will probably still allow you to remove the reel since the reel should pop off the bearing. 6. Once it is assembled, test it by giving the reel a couple turns in both directions and make sure it all works. Printing tips: BASE: I printed the base with supports but used an overhang angle of 85% to avoid supports in the enclosed pockets. There is really only one place where the base needs supports and that is the flat area just above the opening in the back of the part. I printed the base using 0.2mm layer height. REEL: I was able to print this without supports, though it was close. The arms of the reel may need to be supported but everything else should not need them. I printed the reel using 0.2mm layer height. CLIP: Printed without supports and without a brim if possible to avoid the small gaps in the part merging together. I printed the clip using 0.12mm layer height. SLIDER: CLIP: The latest version of this is already scaled to 99% of the original, but if it is not fitting well it may need to be scaled further. Print it without supports and without a brim if possible to avoid the small gaps in the part merging together. I printed the clip using 0.12mm layer height. This part should be glued in after it is fully test fitted and confirmed that everything works. All parts were printed with 3 walls and 15% gyroid infill. These are just what I used so as always, use your best judgement on what works for you and your printer, and good luck! Parts are not oriented for printing. The STEP file is included for easy remixing. Please post any makes and if you see a problem please post a comment. Updates: 4-30-2020: Thanks to feedback, I corrected the model for the base, the updated version is "6I". None of the other parts required updating, but I did update the STEP file as well.
