My take on a mounting bracket for the BigTreeTech TFT35 v3.0.1 (https://biqu.equipment/collections/lcd/products/bigtreetech-tft35-v3-0-display-two-working-modes), since the others I tried didn't quite fit right for me

Included are versions for having the knob on the right (default screen orientation), or on the left (screen flipped in the settings)

Use the stock M3 screws to mount the screen to the bracket, then use either 7mm M3 bolts, or 8mm M3 bolts with a washer to mount the bracket to the printer

The holes for mounting the screen to the bracket might be a little small to just screw into, but I designed them to have an M3 tap run through them

NOTE: I've only tested the right knob version, but the left knob version should work just as well. Please let me know if anything needs to be adjusted

UPDATE: v1.1 rounds a few of the external corners where faces meet, and reduces the thickness of the front by 0.5mm to make it more flush with the printer
