E-Scooter Bag Hook with AirTag Compartment - Fits Segway Ninebot

thingiverse

I redesigned this hook (https://www.thingiverse.com/thing:5777618) to both improve the general look and feel to more seamlessly blend in with the general design of the Segway Ninebot Scooter and I also wanted to make it stronger and more effort to remove. This hook can easily handle a dynamic load of 35lbs (16kg). <h1>Additional parts</h1> Note: All parts are optional 1x Apple Airtag 2x M3x4mm (5mm diameter) threaded heat inserts 2x M3x8mm flat head screws 1x 34mm OD x 31mm ID (1.5mm wide) O-Ring thread lock (eg Loctite Threadlocker) <h2>Threaded Inserts</h2> The threaded inserts go in at an awkward angle. I found it easiest to use a regular soldering iron with a pointed tip and place the threaded insert on that until hot and either quickly (extremely quickly because brass cools very fast) use a pair of bent plies to get the insert partially into the hole and use the soldering iron to finalize placement or just use the soldering iron exclusively <h2>Screws</h2> Screws must have a flat head with a taper to create a snug fit that is flush. M3x8mm is really the only size that will fit correctly <h2>O-Ring</h2> Since the airtag is IP67 which means it can survive being in water for up to 30 minutes, the O-ring isn't strictly necessary however this should prevent any water from getting in at all. This goes around the airtag cover <h2>Airtag</h2> the airtag fit in only one way with the metal/battery cover in first which will hold it in place. <h1>Installing the Bag Hook</h1> As I mentioned in the description, this is intended to be much more involved to remove the hook which means it's much harder to install. To install 1. remove all 6 screws holding the handlebars to the post 1. Remove the handlebars and disconnect the connector cable. 1. Place the Bag Hook on the post (note this is a very tight fit so depending on the accuracy of your printer or filament you may need to upscale the design by 101-102% in your slicer). 1. Re-connect the connector cable (the connector is keyed so it will only attach at the correct orientation, do not force it) 1. Fit the handlebars back onto the post 1. screw in the *TOP* most 3 screws (right, left, front) only leaving the bottom 3 screws empty (Note: you can use thread lock on these screws but because the Bag Hook will cover them and prevent them from backing out it's not strictly necessary). 1. Raise the Bag Hook so that the screw holes line up with the empty screw holes in the post 1. Use a thread lock on the bottom 3 screws to prevent them from vibrating loose and insert them into the remaining 3 bottom holes and tighten until snug <H1>Printing</H1> I would strongly recommend a filament that is UV stable so that prolonged sun exposure does not cause the plastic to deteriorate. ABS or ASA are good choices for this. I used Prusament ASA Jet Black at 50% infill.
