About this model

First, thanks to APBoyer who designed the first seat belt clamp I used for years. It's simple, durable and takes the pressure off your bladder on long road trips. His design is here: I finally decided to upgrade. I thickened the walls, rounded the corners, and added a screw on cap. That last part is important... It keeps the cap from loosening up, and falling under the seat! The new model has been in my car for about 3 weeks in the Phoenix Summer. I printed in higher temp PETG to reduce eventual deformation due to heat & tension. Full disclosure, I normally park my car in the garage. But, it's been out & about in the Sun as well. So far, so good. Be sure to rotate the clamp body to lay flat on the print bed.
