Fridge Blocks! Fun Fridge game for all ages! Inspired by the arcade classic TETRIS this puzzle game allows for tons of fun while learning spatial relations! Have a go at it and see for yourself! I recommend printing 2 sets of pieces for every one game frame. This utilizes 10 magnets, 3 in the frame and one in each of the pieces. The space fits one 10x3mm round magnet. I use the rare earth ones and they work great when combined with the lightning infill at 10% or 0% for the pieces. The frame has standard infill. You'll need to insert a pause in the printing to insert the magnets at layer 25 for the frame and layer 12 for the playing pieces. We've enjoyed meing with the test models on the fridge I think we currently have 4 full sets of pieces and 3 frames! It' a fun blat from the past standing at the arcade with your pocket full of quarters!
