Basis: Makerbase 'MKS TinyBee V1.0_003 SIZE' drawing and the Makerbase TinyBee STEP model, both in the official makerbase-mks/MKS-TinyBee repository.
Catalog version: 2026-10-20

Overall (mm): length 110.1, width 89.13, height 15.8
- PCB 110.0 × 84.0, 1.6 thick, board bottom at 0. Power/heater terminals on one short edge, EXP1/EXP2 LCD headers on the other; USB, SD and the ESP32 antenna on one long edge, stepper connectors on the other.
- Four Ø3.2 mounting holes on a 102.0 × 76.0 rectangle, 4.0 in from each edge.
- Tallest part: the pluggable power terminal block, 15.8 above the board bottom; screw terminals 11.65, EXP headers 10.75, driver sockets and motor connectors 8.65.
- The SD card overhangs the board edge by 5.13 (89.13 overall), the micro-USB by 1.11 and the ESP32 antenna by 1.82.
- Not modelled: plug-in stepper driver modules and heatsinks (they add height above the driver sockets), capacitors, small 2-pin headers and pin tails under the board.
- All dimensions are exact nominal millimetres, true size, with no tolerance added.
