With this mount the RPLidar A1 can sit flat in 3 different orientations. It also has a spot for 1/4 20 nut to mount on a tripod either vertically or horizontally. I used a square one. There are holes for heat set inserts to mount the USB board

additional parts:
M2 screws and heatset inserts for these to hold the little usb thing
1/4 20 nut. I used a square one, but I think hex will also work. Smash this in place

I couldn't find the screws to fit the 25mm spacers the A1 shipped with, so I replaced these with new 25mm spacers and M3 x 10mm screws
