Ender 3 - BTT Pi 1.2 Enclosure Case & TFT35 SPI Screen Display Mount

UPDATE 31/12/2025 - Uploaded .step file

Needed an enclosure for my BTT Pi and TFT35 SPI to fit my Ender 3 v1 while keeping the original casing for the control board. 

Printed in Esun Matte Black PLA but ABS or PETG would be better.

BOM (not complete, need to check bolt lengths required)

6 x M3 T-Nuts    (for 20 series)
9 x M3 Heat Insert L 4mm OD 5mm      (1x for lid, 4x for fan mount and 4x for screen bezel)
7x 6-10mm M3 pan head bolts    (for lid)
4x M3 socket or panhead bolts    (for fan)
4x M2.5 socket or panhead     (for pi)
4x M3 Socket Head Bolt      (for screen bezel)
M4 20mm low profile bolts - for bolting to 4040 extrusion (or re use original)  

Changed the chassis design to fit a BTT pi with accessible front ports, rear cable routing and 4010 / 4020 top mounted fan. Changed the back plate of the TFT35 case to fit the chassis arm with gap for ribbon cable.
