ESP32 Mac

A mini retro-Macintosh enclosure for the Waveshare ESP32-S3-Touch-AMOLED-1.8, designed in Fusion 360 and printed in two parts with no hardware.

The board stays in its own case and drops into a pocket from the front, screen outwards. A separate face plate presses onto six integrated pins (a dab of glue makes it permanent). A normal iPhone USB-C cable runs down a chute inside the body and out through the foot, so nothing shows at the back. Warm air rises from behind the board through a duct to the vent slots on top, and two grooves link the case's speaker and mic holes to the same duct.

What you need

• The Waveshare ESP32-S3-Touch-AMOLED-1.8, in the case it ships in
• A normal iPhone USB-C cable (the Apple USB-C charge cable that comes with the phone). The plug cavity and chute are sized around its slim straight plug and thin cable, so bulkier or right-angle plugs may not fit.
• Optionally a dab of glue for the face plate

Files

• stl/ - print-ready MiniMac_Body, MiniMac_FacePlate and MiniMac_FitGauge
• step/ - the same three parts as STEP
• MiniMac.f3d - the Fusion 360 design (it includes Waveshare's board model, imported from their wiki)
• scripts/ - the Fusion API scripts that generate everything from one parameter block (details)
• renders/ - views, sections and a four-view sheet per part

Printing

Part	Orientation	Notes
Body	rear face down	10-15 % infill, 5-6 top layers, supports on (tree)
FacePlate	face up	no supports; iron the top layer if you can
FitGauge	flat	6 mm slab with the pocket and pins; print it first to check the fit

0.12-0.16 mm layers, 3-4 walls. The body is 56 x 64 x 58 mm on a 9 mm foot, 73 mm tall overall.

The body needs supports: there is one internal overhang that won't print cleanly without them. Use tree supports if your slicer has them. The face plate and the gauge print without supports.

The pocket is 45.4 x 37.7 mm for a case that measures 44.9 x 37.3, sized for a printer that comes out about 0.25 mm tight per side. If the board is loose or won't go in, change POCKET_W and POCKET_H in scripts/build.py and reprint the gauge.

Assembly

Use a normal iPhone USB-C cable (see What you need).

1. Feed the far end of the cable from the plug cavity down the chute, through the foot and out of the back.
2. Drop the board into the pocket with the screen facing outwards, towards the face plate.
3. Reach into the cavity and push the USB-C plug up into the socket.
4. Press the face plate onto the pins.

The board mounts landscape with its USB-C edge down, so rotate the UI 90 degrees in firmware.

Rebuilding the model

scripts/build.py regenerates all three parts from the parameters at its top: pocket size, wall thicknesses, vents, cable route. It needs Fusion 360 with Waveshare's 3D model imported. Download ESP32-S3-Touch-AMOLED-1.8-3D.zip from the Waveshare wiki, unzip the .stp into reference/, then run import_step.py, build.py, checks.py and export.py in that order from Fusion's Scripts panel.
