Automatic doorcloser for people who cant close the door after themself

thingiverse

Hello. One day my mom did leave the door open again and i called after her to close it. She got me an annoyed glare and said something like that: "why doesnt close this door on its own alredy?!" And bam door closed, she out and my mind processing. I didnt have my 3d printer for long and i wanted to try to do something usefull, instead the printing nice thingiverse files to test the printer. So I tested if i could come up with something and so i started constructing. First i measured our door and set the ground with some sketches. Than i started my work with Inventor (grudly because i usually work with solidwokrs). When someone needs the files i can upload them too. And at the next day I had a almost gluefree (The attachement for the door holds by doublesided tape) doorcloser operated by weight of a few marbles. Well the first prototype actual broke on me because the strap wround the doorframe wasnt strong enough, here ist v2 already ;) Well my mom and dad were shocked and proud ^^ In future I will ad a gluefree version to keep it on the door.
