Duplo compatible 2x2 90 degree plane change block
thingiverse
My niece started playing with Duplo blocks and, much to my surprise, there are no blocks that allow you to change the plane orientation in the normal sets. This makes things like affixing propellers rather ridiculous. I didn't find any blocks on Thingi that were both easily printed and did what I wanted, so I made this version, which prints as two pieces and is then epoxied or super glued together. Intended for PETG printing, you might need to adjust tolerances for your printer (use the attached STEP files to do so parametrically). Fit is as tight as the original Duplo blocks. * Recommended material: PETG (PLA is not flexible enough for a nice fit and ABS shrinkage sucks). * Recommended layer height: 0.15 - 0.2 * Recommended perimeters: at least 2 * No supports needed * Give the "short" side of the block (it's about 1.5mm shorter from the pegs to the edge) and the back of the flat piece a quick sanding, then attach with either super glue or epoxy (I used cheap epoxy since it's less brittle)
