This model allows you to attach your multiboard grid in the side frame of a shelf. It might be a bit specific to my usecase but some might find it useful, or help design their own.

This model is relying on this design to be linked on the grid : https://thangs.com/designer/JetFish76/3d-model/Double%20Sided%20Flush%20Snap%20For%20Multiboard-1353138 so you'll need to print one per bracket, but since it is multiboard-compatible, you can plug in whatever you want :)

The bracket has a recessed slot allowing a small adjustment of the distance between the grid and the pole you are mounting it on. You can print a housing for your bolt (I provided a simple example in the files) that will hold the bolt ald also secure its placement horizontally. The slot is 5mm wide, and the bolt housing is for an M5 bolt ( 7,8mm wide, 3,66mm high).

I find the grid is quite well secured after intallation. My own grid is quite small though, it is 13MU wide and goes down the shelf with 8MU per plate. I put one of these brackets every 7 to 8MU.
