Fully Printable Doorstopper

I didn't want to use a slab or heavy thing to block my automatic closing door when ventilating my apartment, so i designed this automatic doorstop. It is finished using a metricn M5 hex head screw as bolt, alternatively you can print a fitting piece if you like.

Just put the parts together, put the bolt in and glue it to the floor using double sided tape. To release the door gently push the lever with your toe.
