The key to printing a durable stethoscope holder is to print the main body and the clip separately, and to print the clip lying on its side. Glue the two parts together using cyanoacrylate or epoxy glue.
When it comes to cleaning the stethoscope holder, I’ve had one lying in a small tub of 85% isopropanol and another in a tub of regular 70% ethanol for two months – no apparent degradation. Just remember to not use alcohol with added glycerol or perfume, as it can lead to a buildup of gunk on the stethoscope holder.
I like the regular stethoscope holder printed in simple white PLA or Eryone bronze PLA, and the heart stethoscope holder in Fillamentum PLA Extrafill Pearl Ruby Red.
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!

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.
