Waveshare ESP32-S3-Touch-LCD-1.28 Desk Stand, Tilted, No Supports

Tilted desk stand for the Waveshare ESP32-S3-Touch-LCD-1.28 round touch display: USB-C from the side, BOOT/RESET reachable, prints without supports. What it is A small desk or shelf stand that turns the Waveshare ESP32-S3-Touch-LCD-1.28 into a finished round display for Home Assistant / ESPHome dashboards, a clock or a gauge. In daily use only the USB-C power cable connects; it leaves from the side. The SH1.0 GPIO connector and the battery socket stay unused, and BOOT/RESET are pressed with a pin when you flash. Features - Modelled on Waveshare's own STEP model and dimension drawing, not on photos: 0.3 mm clearance around the 38.51 mm glass - 34.0 mm front aperture with a 0.6 mm chamfer: the whole 33.4 mm active area and the touch glass stay free, the bezel holds the glass edge - USB-C hole lined up with the receptacle (receptacle face 0.9 mm behind the outer face, so normal cables seat fully) - 2.5 mm pin holes in the back lid over BOOT and RESET - Press-fit back lid with a small pry notch, no screws - Display leans back 15 degrees on an integrated foot - No supports: the body prints face down, the lid prints flat - Why this size: the puck is 11.5 mm deep because that is the module (8.4 mm), the 1.2 mm bezel, 0.3 mm air and the 1.6 mm lid, nothing more. The only openings are the display, USB-C, BOOT, RESET and the lid notch.
