This model consists of a 300x300 base plate with slots for 25 tiles. This is ideal for 3x3 ArUco patterns for ground control of drones.

This design is heavy enough (~610 gm) to withstand wind and vibration. It's weatherproof. The tile based design allows for customisation of patterns, or for multiple colours.

Requires square m3 DIN562 nuts and some 20mm m3 screws. I printed the base out of PETG and the tiles out of ABS.
