87 mm Gym Bottle Collar with Phone and Keyfob Mounts

Keep Your Phone and Keys with Your Gym Bottle

Keep your phone and keyfob together with your gym bottle using this 87 mm bottle collar. The supplied photos show a split collar fitted around a bottle, with a circular phone-ring mounting area on one side and a magnetic keyfob docking feature on the other. Two printed bolts close the collar, and a separate keyfob holder has a threaded cap with a driver-bit insert. The download contains the original Bambu Studio 3MF project in one ZIP archive. Its two plates include the collar, keyfob components and two printed bolts. Color assignments and saved print settings are retained. Separate STL or SolidWorks source files are not included. The bottle, phone, keys and purchased hardware shown in the reference images are not included in the download. The folder identifies this as the 87 mm version. Check your bottle's dimensions before printing; universal bottle or phone compatibility is not established by the supplied files. The saved project uses PLA, 0.2 mm layers and 15% gyroid infill. Automatic tree supports are enabled, with supports disabled on the two printed bolts. Slicing both plates with the saved Bambu Lab A2L 0.4 mm nozzle profile estimates approximately 183 minutes and 65 g in total. Actual time and filament use depend on your printer and settings. Required purchased components supplied by the creator are a driver bit, a keyfob magnet and a magnetic phone ring. The creator specifies a tight sliding fit for the hardware inserts. Fit the bit, keyfob magnet and phone ring into their corresponding printed recesses. The keyfob cap screws into its holder.
