SLAMTEC RPLIDAR A1M8 360° laser scanner: base outline, 4 mounting holes, scanning head and motor — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/slamtec-rplidar-a1m8/ (sheet CC BY 4.0) Basis: SLAMTEC's official RPLIDAR A1M8 2D drawing, with the base outline, hole depths and under-plate parts taken from SLAMTEC's official 3D model. Catalog version: 2026-10-20 Overall (mm): length 96.74, width 70.28, height 51.0 - Upright, lowest point (motor connector) at 0, top of the scanning head at 51.0. Base plate from 21.0 to 26.5 (5.5 thick); the rotating disc is Ø70.28 and the head Ø70.0. - The head axis sits 35.14 from the head end of the 96.74 base; the Ø32 drive motor hangs below the plate, flush with the opposite end. - Four Ø3.0 mounting holes through the base plate, each with a Ø5.0 × 2.0 counterbore at the plate top: 70.0 apart along the length, 56.0 apart across at the head end and 40.0 apart across at the motor end. - Measured from the head axis, the head-end holes sit 28.0 toward the head end and the motor-end holes 42.0 toward the motor end. - Modelled: base plate outline, holes, skirt and PCB under the plate (down to 15.0), motor and its connector, pulley, rotating disc and head. Not modelled: drive belt, plate ribs, head window and the loose cable. - All dimensions are exact nominal millimetres, true size, with no tolerance added. hole x from head axis (mm) y (mm) diameter (mm) 1 -28.0 +28.0 3.0 (Ø5.0 cbore) 2 -28.0 -28.0 3.0 (Ø5.0 cbore) 3 +42.0 +20.0 3.0 (Ø5.0 cbore) 4 +42.0 -20.0 3.0 (Ø5.0 cbore) Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - SLAMTEC: RPLIDAR A-series support and downloads — web — Publisher's page; dimensions are facts — https://www.slamtec.com/en/Support#rplidar-a-series - SLAMTEC: RPLIDAR A1M8 R1 2D mechanical drawing (PDF) — web — Publisher's page; dimensions are facts — https://download-en.slamtec.com/api/download/rplidar-core-a1m8-r1-model-2d-pdf/2.0?lang=en - SLAMTEC: RPLIDAR A1M8 R1 3D model (IGES) — web — Publisher's page; dimensions are facts — https://download-en.slamtec.com/api/download/rplidar-core-a1m8-r1-model-3d-igs/2.0?lang=netural Free files (CC BY 4.0, Xem Studio; STEP + STL, 1 parts): https://xemstudio.com/files/hardware/slamtec-rplidar-a1m8/index.json API: https://xemstudio.com/api/geometry?object=slamtec-rplidar-a1m8
