duplo-car-compatible couplers

thingiverse

I'm just another Lego-compatible brick, or better said, a set of two bricks for coupling two Duplo car bases. The 2x2 module I used is also included. Test with real Duplo cars: https://youtu.be/OeL-DKnaXXk The geometry and the size are my rough estimate. The tolerance between the bricks is 0.15mm on each side, so 0.3mm between two bricks. The tolerance between the stud and the brick-bottom is 0.08mm on each side/contact. If your printer is worse or better calibrated than mine, the bricks might not fit. The blue ones are the first version, with a 0.4mm smaller height. The red ones correspond to the files with V2 in the name, which have a Duplo-like or Duplo-compatible height. Happy printing!
