This is a big 46 x 30 x 8 cm wall shelf that prints in place in one go on one plate.
The frames have intersections and one fits into the other so it can be printed on one go.
You can use any filament you like, the 3mf file uses bambulab PLA and prints with the backside up to ensure that the visibly side is on the plate. The number of top layers is used to make the backside strong enough to hold screws for wall mounting. Fell free to mount it in any direction there are plenty of mounting holes so any direction is possibly.
The author marked this model as their own original creation.
