juh shared this project on Thingiverse!

Fully printed, no assembly, print-in-place fin ray grippers, printed with plain PETG, no TPU flexible filament needed.

The connectors are compatible with fischertechnik. The grippers’ angle is 16°, so that you can use two Winkelsteine 7.5 to get a near parallel setup.

Dimensions: 78×30 mm, 7.5 mm or 15 mm height. Use the versions with custom brim for better bed adhesion.

You’ll need a well calibrated printer/filament combination. Elephant feet, stringing, and particularly overextrusion will result in joints which are not supple enough for a smooth operation.

Post printing: Clean the joints from filament remains and gently break them loose. You can improve suppleness by manually bending each joint individually with one hand a couple of times while gently pressing it together from above and below with the other hand.

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!
