[Updated] Duplo compatible building block 2x4 - no support required

prusaprinters

<p>This is a Lego Duplo compatible 2x4 Block, which can be printed without support. Thanks to your comments I tried to improve the brick to better integrate with original Duplo Bricks.<br>I also tried smoothing the edges, but in case you still think it is too sharp, please use light sandpaper to improve the edges.<br><br>For optimal print use small layer heights and 0.4mm nozzle. I used PETG for the test prints, but PLA will be better suited for children. Make sure your printer is properly calibrated (esteps) for optimal fitment. It can be a bit tight to insert the printed bricks in the bottom of the original bricks, but not too tight. It is just holding pretty well with the current model.<br><br>I'll try to add some additional bricks in the future, to give a bit more variety.<br>Let me know how you like the new iteration!</p>
