Murray Clark shared on Thingiverse:
The target itself is a moving one piece print with hinges. The second part is a small flat strip of PLA that is used as a return spring. Both parts only uses a bit over 60gm of PLA at recommended setting (including Raft). As an alternative to printing a PLA spring you can cut a similar size strip of flexi / springy plastic from an old plastic container of some sort.
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!
