I checked Thingiverse for seat belt slides, but could not find one that was easy to adjust. I decided to design my own. This one has 3 parts to be assembled. It uses sponge window foam to function like a contraction spring. Works perfectly (smooth) and looks great.
This design uses a press fitting so it can be assemble around the seat belt in the car. I used MD Sponge window seal 3/8″ thick and 3/4″ wide 10 feet is about $4.00 US. (see photo of package) Actually you only need to cut a 50 mm long section for each clip. The foam has adhesive on one side so it can be adhered to the clip before it assembled. The last plate has smaller slots and is a simple press fit onto the two leg spacers. Once assembled around the seat belt, you can simply press the last plate onto the two legs. If you need a tighter squeeze on the belt, you can use a pair of channel lock pliers to press the end of each leg into the final outside piece a bit further. This design uses 8 mm gap for about 9mm of foam thus it always has a small amount of pressure on the belt, so simple press fit should work fine.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7:30pm ET! To join, head over to YouTube and check out the show’s live chat and our Discord!
