BigTreeTech BTT Pi 1.2 Case for Wall Mount or 2040 (dovetail style)

This started off with the idea of the Dove Tail mount by Josh Park(@JoshPark_68426), but for the BTT Pi 1.2.

With the base from lotohov(@lotohov_279923) and their Orange Pi LTS 3 Case, and the 3D model supplied by Big Tree Tech the case was design nearly from scratch. The BTT Pi 1.2 is not based on the Raspberry Pi hole pattern and uses 2.5 mm screws instead of the 3mm used on the Raspberry Pi, and the Orange Pi LTS 3 models.

These parts were modeled off the supplied 3D model from BTT, but after the first print some components were slightly different. The audio jack, and infrared connectors were shown as flush mounted to the board in the 3d model but were different on my physical board. The external power connector showed as a much higher screw down terminal block compared to my physical board. The largest model between the 3D model and my physical board were used in the final models.

All motherboard connectors were model out through the top and should allow full access. My testing only included the Wi-Fi antenna, Fan, external power and SD Card.

There are 3 tops available:

-BTTPiTopCase30mmFanInsideNoHeatsink

-BTTPiTopCase30mmFanInsideHeatsink

-BTTPiTopCase40mmFanTop

Both of the 30mm fan model mount inside of the case, but if the heat sink is used the model BTTPiTopCase30mmFanInsideHeatsink should be used as it is 8 mm taller and allows room for the heat sink with clearance. A 30X30x8mm fan was used, and pan head 3mm screw was used with a length of 10mm (3mmx10mm pan screw)

The BTTPiTopCase40mmFanTop will screw the fan into the case from the outside and should have a fan grill (I chose my favourite). The screws required are 3mm, and length will depend on fan height. Photos used 3mm x 25mm tapered head screw for a 40mmx40mmx20mm fan.

You will require 3 x 3mmx8mm taper head screws to connect BTTPiBottomCaseCombo to the Pi dovetail part. To connect the top to bottom 2.5mmx12mm hex cap screws will be required. **10mm length should also work with about 1.5mm into the top.

I have included Josh Park(@JoshPark_68426)’s model of “Pi dovetail” as it will be required.

Then use either Josh Park(@JoshPark_68426)’s Wall mount:
