Trapdoor

Traphouse/Trapdoor Assembly for Kids. Push the first step and you LEGO Mate will fall into the staircase. Tips: print separately Springlock 0.12mm slow, PETG Door PLA or PETG 0.12mm slow: I have added the Legs to support the fall- down but they are brittle. Alternatively you can print the non leg version und fasten rubber bands with M3 Screws Step: finish with some wet sanding to have low gap and low resistance Main: Print in natural position. Requires good amount of support but this gives the cleanest look. get yourself a role pin set to connect the rotational joints. I have used 2.5 x 8 and 2.5 x 16mm Feel free to copy and modify the assembly: https://cad.onshape.com/documents/5685bcf09944a92412e2c72b/w/73ee08159ca9429c7694f69b/e/32c8b714e7dd03ddf5203c6f?renderMode=0&uiState=6976180d9984d4057d4a8501
