RPLiDAR C1 Mounting Holes

Hello everybody, I recently got a rplidar c1 and cant find the dimensions for the mounting holes anywhere. I don't have any tools except a tape measure. do you think it's precise enough? also if anybody knows I would be uber grateful if you shared it. Also if you guys have any recommendations for using it. I don't want to use a gui software because it feels like cheating but I know a decent amount of python so if you guys know any libraries or anything like that. I am new to lidar but want to build a telepresence robot to make a semi self driving robot.
