there seems to be no easy to assemble, infinitely stackable and universal (means all pi B models) case for raspberry pis. the one by CmdrSoyo (@ZorasTech_2340807) was the closest i could find, so i modified it.
This is by no means a complete or even professional redesign. i just took the parts i wanted and somehow made them work for me.
I'd still appreciate comments and suggestions though. if the original creator wants to adapt this stackable function in a more clean and intelligent way, i would be very pleased with that
Instructions:
the lowest raspberry in the tower can still be screwed in, the rest of them gets held by pins in the mid part
The author remixed this model.
fused together top and bottom to create a middle part. also added pins to center the pi since you cant use screws in the middle
