This is a 30x120 degree x22 Marker Block for the MMT (Modular Marker Tower) system.
Preferably should be used at the bottom of a marker tower, to not block the view higher up.
It is also very suitable as a standalone marker tower to position at a distance from the object being scanned.

Add reflective markers to the block so that it creates unique patterns for every TT printed.
3rd picture has an example of marker patterns, but many more can be created.

The markers for this item are diameter 10 mm (6 mm reflective center).

Choice of filament material for the MMT:
This part was designed for use with Bambu Lab PLA Basic, but can work with other regular PLA of similar quality.
Matte PLA or Silk PLA should not be used due to their weaker mechanical properties compared to regular PLA.
 

Choice of filament color for the MMT:
Gray: Works well when scanning most objects in marker mode, and it will also work to assist tracking in geometry mode.
Black: Works well when scanning black parts, as it can otherwise risk overexposing the marker block, leading to loss of tracking.

The 3mf file has 1 pcs ready on the plate to be printed.

Added an introduction video for the MMT-system that you can find here:

(I had no idea what to call this thing, so I just called it TT, for the TwentyTwo number of marker positions…)
