A machine that my partner needs to use for work comes with really terrible cables that fail all the time due to a lack of adequate strain relief. I tried several methods to reinforce them for her, and while productive, none of them worked super well. So I tried something else and was really pleased with the result.
There’s some built-in support material (brim?) on the bottom that you need to remove. Without it I was unable to get good yield. It’s 0.15mm and therefore 1 layer thick with the settings that I used. It can be trivially broken off with tweezers.
Most other strain relief designs that I’ve found on Thingiverse are fully round and printed with the central axis vertical on the plate. This one is rectangular to provide a build surface, allowing it to be printed with the central axis in XY. Doing that eliminates the need to have support material inside the coils, substantially reducing post-print manual cleanup.
I wouldn’t be surprised if it’s possible to print it without the brim, but with a stickier build plate. I’ll give that a shot (e.g., with glue stick) and if it works out OK, will post a model without the brim.
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!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
