Flip-to-start Pomodoro enclosure for the Waveshare ESP32-S3 Touch AMOLED 1.8. It holds the complete device in its factory black enclosure (45.2 × 37.6 mm). The device drops into a snug pocket in the body. A front lid with the screen opening clicks on with four hidden cantilever tongues and an 8 mm deep frame. Matching scallops under the seam on two faces are enough to take the lid off by hand. A chamfered rectangular USB-C port sits on the +X face. The cavity behind the device is a light honeycomb so it prints without supports.

With Buttons	Without Buttons

Four ready-to-print variants live in subfolders. Each can be with or without printed PWR/BOOT push-buttons, and with or without side engraving:

• buttons/labeled - push-buttons and default 5 / 10 / 30 / 60
• buttons/unlabeled - push-buttons, blank sides
• no_buttons/labeled - no button bores, default 5 / 10 / 30 / 60
• no_buttons/unlabeled - blank cube

The four side texts are the LABELS tuple in pomodoro_timer_enclosure.py, in order +Y, +X (USB), -Y, -X. Change those strings and re-run the script to engrave your own presets on the labeled variants. Empty strings skip a face.

Assembly (button variants): drop the two buttons into their bores from inside the body, lay the device into the pocket, then press the lid on until the tongues click. The button positions come from the official board STEP model; adjust BUTTON_Y and BUTTON_Z if the factory case places its keys elsewhere.

Main parameters:

• Case size: 52 × 52 × 46 mm
• Wall thickness: 1.8 mm
• Corner radius: 3.2 mm
• Device pocket: 37.9 × 45.5 × 15.5 mm
• Screen window: 30.1 × 36.3 mm
• USB-C port: 14 × 10 mm bore, chamfered to 15.6 × 11.6 mm
• Engraving size/depth: 22 / 0.55 mm
• Rear honeycomb: 11 mm pitch, 0.8 mm walls
• Lid frame: 8 mm deep, 0.25 mm clearance per side
• Lid retention: four 12 mm tongues, 0.45 mm engagement each
• Grip scallops: 16 × 2.2 mm, 1 mm deep, on the 5 and 30 faces
• Push-buttons: 4.4 × 5 mm bores at ±10.5 mm, 0.5 mm free travel, caps 0.3 mm below the face

Files:

• pomodoro_timer_enclosure.py - Parametric source
• buttons/labeled, buttons/unlabeled
• no_buttons/labeled, no_buttons/unlabeled
• Each folder has body and the same wide-channel lid; button variants also have button (print 2)
• STEP files are available beside each STL

Based on vumaq's original Printables model. The board fits the original stand, but the opening below it is too small for my USB-C plug and access to the buttons. This version extends the lower body 15 mm and makes one 34 mm wide opening under the board for both buttons and the cable. It connects to the 16 mm rear cable channel; the side seating surfaces remain in place.

• Size: 50 × 50 × 55 mm
• To regenerate: download ticker32-cfc1.stl from the original model, place it next to esp32_table_dock.py, install numpy and manifold3d, then run the script.
