My goal was to make something big enough to be useful but small enough to not get in the way or add significant bulk to the case build. The screw head sockets are shallow enough that the knob stops maybe a tenth of a millimeter or so short of the screw head’s bottom lip, which helps ensure the knobs don’t end up rubbing against the tent legs.
The socket depth is 3mm and the knob length is 7.5mm, so you should expect about 4.5mm to be added to the length of your screw head. The knob’s diameter is 10mm.
I’ve included three STL files with three different socket diameters for the screw head, in case that’s the only variable you need to tweak. I find the 5.75mm socket best fits the screws I bought, though your results may vary depending on the filament you use and the size of your screw heads.
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.
