This piece is designed to mount on a roll bar on a Miata to improve retraction of the seat belts. One will be required for each side - simply flip the print on-axis for the other side. The default version is for the Driver's Side.
- 3D Printed Roll bar seatbelt guide (this thing)
- Electrical Tape (~10")
- Zip-Tie that can fit through the hole on the seatbelt guide
Step 1: Remove interior panels as appropriate to expose the seatbelt retract mechanism and roll bar.
Step 2: Wrap electrical tape around both "tips" of the C on the 3D printed seatbelt guide - this is to increase friction against the roll bar, so it doesn't move once installed.
Step 3: Slide the zip tie through the hole in the seatbelt guide
Step 4: Feed the zip tie around the roll bar
Step 5: Clip the seatbelt guide onto the roll bar, tightening the zip tie around the guide.
Step 6: Experiment with placement on the roll bar to optimize seat belt retraction. It may not be perfect, but it is a noticeable improvement on my Miata.
