3D Printed Holder for LED Throwies

3D printed a simple holder for coin cell batteries and make LED throwies that’s re-usable. Just pop in a coin cell and press fit them together. You can slide in an LED and take it out to turn it off or change the battery. The design is free to download and easy to print so you can make batch of them. You can get your students involved by having them setup the parts for 3d printing.

This is could be pretty cool way to have students learn how to light up their first LED. Have the kids use the LEDs in other projects. Just change out the battery when its done. We think young students can learn by making and hopefully get them interested in how electronics work.

STEM LED Starter Kit

 

These types of projects can help STEM educators get their students excited about learning electronics and making. Educators can use LEDs to teach kids how they work and get them involved with the making process. 

 

The idea is to put a kit together for a classroom or workshop using just a few parts.

DIY Slime

Whip up a batch of slime and throw in some LEDs to make it glow! Use transparent colored slime to make a soft diffusion. You can stretch and squash the slime without having to worry about getting poked with the LEDs because they're safely housed in a 3D printed holder.
