for usb i used cables like the one on the picture, just cut the males of and solder it directly to your raspberry pi. You will find the cables on amazon or banggood.
for mounting the case to the middle part i used screws which where also used to mount fans in a PC (Computer Cooling Fan Mount Screws). Same for the Backplate. You’ll find them also an amazon
i used 30x30mm 5v fans
for mounting the base to the middle part you can use screws with 3mm diameter and 20mm length
in the base you can mount iron plates to weight it down
— plate size 80x60mm
— holes for plates 68x51mm and 3,5mm use also 3mm screws
to prevent the stand from sliping around, i used a 1,5mm mat which is also used in trunk of cars. Use a spray glue to fix it 😉
any questions? Just ask 😉
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.
