Ortur Base to Duplo Blocks
thingiverse
I went through a bunch of PLA to get this right. I wanted a drop in Ortur LM2 base solution that scaled up with Duplo blocks as I do a number of different sized items. I have included the Sketchup files in case you want to modify. I included holes to screw in your base 1/2 size Duplo block to your board.
