Summary

BIGTREETECH Pi V1.2 ENCLOSURE

I've been testing different designs and this is the most effective in terms of heat dissipation:

BASE_BBT_PI_V1.2.stl
FAN_SUPPORT_BBT_PI_V1.2.stl

The red heatsink BTT's Pi is provided with, is good and generous.
This said, I still recommend active cooling if you plan to place this Pi inside your printer (or in any other closed spaces whatever your Pi is supposed to do).

Tests done so far with only passive cooling (OS: Armbian 23.5 Bookworm):

Octoprint on Armbian (RAM load around 240 MB)
Armbian + LXDE core (RAM load < 400 MB).

It does simple jobs nicely, but climbs up to 60C (in summer).

Temperature readings running a 4010 (OS: Armbian 23.5 Bookworm+LXDE core):

45/46C under load (copying files while reproducing multimedia content trough LAN)
Running Octoprint on Armbian this BTT PI remains at 39/40C
BTT's Klipper remains around 40C

Things you need:
5 mm long pieces of PTFE tube to make spacers.
M2 or M2,5 screws and nuts to fix the board to the base.
To fix the fan support I used small 12 mm wood screws
M3 x 12 or 14 mm. Washers and nuts or locking nuts to fix the fan

Get a 5V 4010 fan to be plugged to the board.

To fix the enclosure to your printer you can use 2 flat round head wood screws. This probably requires drilling 2 little holes into your printer's enclosure (see last picture).

I don't recommend the use of double sided adhesive tape for this purpose.

UPDATE as per 2023.08.18.

3 new base-STLs were added.

b1 and b2 look a bit bulky but will facilitate attachment to frames made of aluminium profiles 2020 / 2040.

In addition to the small stuff mentioned above BASE_BBT_PI_V1.2_b1.stl and BASE_BBT_PI_V1.2_b2.stl will require:

2 x T-Nuts (4 mm bore)
2 x M4-10 mm and
2 washers

A really nice little board!

Enjoy!
