This design allows you to hold an A1 Lidar from RPLidar to the Turtlebot3 waffle plate.
The waffle plate is a module robot base platform used in the open source Turtlebot3.
The attached 3mf file includes my selection of variable layer height. Taking advantage of .3mm at the base for maximum strength with .1mm at the top of the “feet” to allow for a nice fit.
UPDATE: v2 is shorter and more compact, with more mounting hole options.
