I found a cheap but awesome Bluetooth receiver with APTX Bluetooth 4.0 capabilities and with a dead simple but gorgeous controller - it's ~22 EUR now on amazon.
I tried to find a proper placement for it in my car when I realized the useless coin holder in the centre console would properly hold it.
I redesigned my coin holder from scratch to hold the Bluetooth receiver properly. There are 3 STL files:
- BT controller holder.stl is the new coin holder itself
- wire fixer.stl is the simple plug which drives the controller cable and hides the cabling hole
- drill mask.stl is a simple cutout from the coin holder. The BT controller comes with a magnetic mount support. You have to remove this and have to drill a hole to the bottom part of the controller enclosure. In order to help the proper hole positioning, I made this simple mask so just push the bottom part of the enclosure into it and drill it through with a 3 mm drill using the mask's guide hole.
Here's a blog post about the design process (sorry folks, Hungarian only).
- 1 pc M3x16 bolt
- 1 pc M3 nut
- 2 pcs 16mm long self tapping screws with ~3mm diameter
