Duplo Brio Adapter Remix

Update V2: I completely rebuilt the Duplo connector.

I changed three things of the original "Minimalist Duplo - Brio, IKEA, Wooden Train adapter" with Tinkercad in order to fit my needs:

1. I reduced the inside height of the Duplo connector to only support normal bricks (4.8mm height inside). When using two Duplo bricks beneath it, it leads to the same height of the track compared to the Brio lifting bridge (an old model). I had to adjust the recesses for neighbouring Duplo bricks as well. 
    
2. I added 1mm to the male connector neck in order to be more tolerant for different (old) Brio trails.
    
3. I completely rebuilt the Duplo connector on my own, especially because the inner female connector was not correct. 
    

Also note my underpass trail model in the picture: https://www.printables.com/model/397087-brio-lifting-bridge-underpass

Recommended print settings: Infill 15%, no supports, layer height: Variable for smoothing some parts (see second gcode file). I used Prusament PLA Gentleman's Grey - see pictures.

Thanks for sharing the original model @András Bognár. 

Update V3:  I increased the bottom skirt (about 1mm) according to your feedback. Be aware: I did not change the gcode files yet to V3.

Update V4: I rebuilt the male connector and fixed the cutouts of it - thanks to @YukikoAnonuev_936946 and fixed another error of V3.

Update V5: Fixed the height of the center stud, thanks for pointing out @HajoPiltz_1291097!
