Box Size

Shape Rectangular Cylindrical Outer diameter (mm) Outer width X (mm) Outer depth Y (mm) Outer height (mm) Wall thickness Floor thickness Corner radius

Removable Side Plates

North wall (back) East wall (right) South wall (front) West wall (left) Plate thickness (mm)

Each checked wall gets its own opening sliced from the top rim; vertical rails inside hold a plate you can slide out and back in.

PCB Mount

Standoff wall Cut lid where a board sticks through

Each enabled board gets four posts on the floor at its mounting holes, with a heat-set insert bore in the top — screw the board down from above. Drag a board in the 3D view to position it, or type exact coordinates. The translucent boards are a fit guide only and are never exported. ESP32 presets (≈) vary by manufacturer: measure your board and adjust, or pick Custom.

Set Tallest component to whatever stands highest on the board (a USB jack, pin headers) — that, not the bare PCB, is usually what hits the lid. With Cut lid ticked, a window is cut clean through the lid only for boards whose total stack is taller than the box, so the board pokes out. Boards that already fit leave the lid untouched.

Edge Fillets

Lid top fillet (mm) Body bottom fillet (mm)

Rounds the lid's top outer edge and the body's bottom outer edge. 0 = off. Bottom fillet is limited to the floor thickness; increase floor for a larger radius.

Body Engraving

Engraved vertical lines

Rounded (half-round) vertical grooves evenly spaced around the cylinder wall, with smoothly tapered ends. Bottom offset is measured up from the floor. The rounded top taper keeps it support-free to print.
