This thing is a adapter to mount a magnetic phone mount to your seat belt. Have you ever been driving down the road, a phone call comes in and you answer it on speaker, but you can barely hear or the caller can barely hear you? As a result you have to pick the phone up and hold it to your face or find a better place for it. Well this thing solves that problem. I took a phone magnet for AC vent mounts and added it to a seat belt adapter. This thing will allow you to put your phone closer to your mouth and ear to better hear your phone call on speaker while still remaining hands free.
Currently this is designed to fit on a somewhat normal 47mm wide seat belt. If you have wider seat belts let me know and I can extend the width. I have included dimensions in the thing files.
There are two versions, one with holes that have recesses that fit the raised part on the back of the magnet and one w/out holes to mount the adhesive backed magnets.
Extra Hardware for Adapter w/ Holes
1x M3 washer
1x M3x12 Screw
After some trials and a little use I made some adjustments to the adapter.
-Ridges to contact and hold the magnet.
-I have made slight changes to the thickness.
-All of the edges have been curved.
-Arms are tighter to reduce movement.
-Friction points on the inside of the adapter.
For the adapter without holes use 10% as the layers are close enough that it will print the same with or without infill. The thing with holes is a little wider on the main face and does require some infill. Whether it's 10% or 100% it will print the same. I printed this with a brim to give a bigger foot print.
When printing this thing turn the model so it is printed longways along the Y-Axis. I ran into some consistent heating issues when printing on the x-axis. The model will work like a deflecting wall that will move excessive air onto the heated block causing the extruder to cool below the filament's melting point. Once the model was printed on the y-axis there were no problems at all.
