MMT - Octagonal Frame - x8

This is an octagon frame system for the MMT (Modular Marker Tower) system.
The octagon frame consists of 4 pcs Frame Side pieces, or 8 pcs Frame Side Split pieces.

To connect the pieces, simply hold them together at the ends, and screw on any MMT-module on top.
You can also screw in any of the modular pieces underneath, like the different bases to elevate the frame off the surface.

If you use the parts “MMT - Creality Turntable Camlock”, then you can attach this frame to a Creality Turntable. (Optional)

You can also place this on multiple levels, to give more stiffness if building a really large modular tower.
The bottom pieces should be the Frame Side pieces, as it will give the best stiffness.
On top, it should be the split pieces to make sure you can properly mount any additional levels.

There are several holes for D6x3 magnets, both on top and bottom, so that you can use it to secure the other 3DSM marker blocks to it, and as well secure the modular frame system to a ferrous surface.

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 for the different sizes has the following number of pieces per buildplate to be printed:

Octagon Frame Side - has 4 pcs ready on the plate to be printed for a full level of the frame.
Octagon Frame Side Split - has 4 pcs ready on the plate to be printed, for half a level of the frame.
