I do intend to make the SketchUp files available for download soon. With these files you can resize my design or make other adjustments to fit your needs.
This is actually a continuation Pi 2/3 Wind Tunnel page. It is after all the next logical progression wouldn’t you agree?
Please note that this design is specifically for the Pi3 utilizing no addition hardware, i.e., SSD drives, wifi/bluetooth dongles, ethernet cables. It will support a LED to alarm on temp violation and a 5V DC fan for cooling. Any hardware beyond this will require tunnel extensions and/or couplers, etc. as well as modifications to the assembly instructions.
What you will need:
- a Raspberry Pi3 w/micro SD card loaded with your choice of OS
- standoffs – M2.5 –and M3.0 M/F, F/F in various lengths. For the Pi nylon is preferred because it is non-conductive
- a 3D printer or access to a 3D printer (a friend or two)
- ability to make connectors and to solder
- M3 nuts and bolts – various lengths (the holes are sized slightly larger then M3 to allow some movement.
There might be a need for tools necessary to fashion connectors. I am intentionally going to avoid the electrical side here. I will make suggestions but you assume all responsibility for damage resulting from electrical wiring either to your Pi or environment. There I have said it.
Before going further I need to state that the total print time for the PiVE is ~61 hours.
The PiVE consists of 4 complete “cells” joined together. I will break down each piece with quantity and print time. The required pieces for a single cell are:
To make the PiVE you connect four cells together. Here are the parts and times for those connectors:
Assembly will provide a general overview to assembling the PiVE. References to bolt, standoff sizes will be called out where appropriate as will part placement which if done incorrectly will cause lost time.
