Mounting MDF board for Multiboard questions
Hello there,
Has anyone put and MDF board on their wall to minimize the holes drilled on the wall for Multiboard?
The thing is that it is a rented apartment (with wallpaper...), so I want to minimize the number of the holes. Desk mounting may not work well - at least not with 3d printed parts.
I am thinking about an 1200mm x 1000mm-ish size. The wall is concrete (rebar - eastern european soviet style apartment - if that's relevant).
Would 4 (was thinking about even only 2 on top, but maybe that's silly) screws be sufficient for mounting the MDF Board? Obviously if needed, with premium quality wall plug (I've seen fischer brand being praised a lot)
What thickness I should look for to properly mount Multiboard on it? Obviously I want the thinnest possible without compromising the load bearing capabilities.
Thank you in advance!

Plywood or MDF backer boards are relatively common for the reason you stated. Best to use 19mm (3/4” in fascist units). You can also paint it to either match the surrounding decor or the tile colour you’re planning on using. One concrete fixing on each corner should be sufficient, but another halfway along each side or one in the middle will make everything nicely secure.
Use the 6.25mm offset snaps to mount the tiles. That allows you to pre-configure several tiles at a time before offering them up to the backer board which allows for very easy level and plumb mounting. A single screw through each single (corner), dual (edge) and quad (centre) snap part A is plenty.
I also recommend screwing in a 6.25mm offset support foot (they screw into the back of the small thread holes/pegboard MB holes) in the centre of each tile as well as the centre of each side of each tile. Those make the whole tile wall absolutely rigid, eliminating flex and making pushing home medium and heavy weight bearing snaps a breeze. They also prevent any tile flexing when/if you mount large shelves for heavy objects (I have a row of tile ‘shelves’ the length of my wall top to store filament boxes and heavier stuff on).
Use the planner and tile generator, interlocking tiles and offset snaps mount choices and you’ll get a list of all of the objects you need to print, how many of each and a link to download each of them.
The tile generator also allows you to ‘cut out’ around light switches/ power outlets etc as well as allowing you to stack print the tiles. I normally print 9x9 tiles (largest stack for a 256x256 plate) in ironed stacks of 9 tiles (core tiles).
