We had to start baby proofing everything and I saw a similar item on thingiverse from user Remivans https://www.thingiverse.com/thing:3149086/files and it inspired me to make something very similar but I started from scratch because his was for a 40mm door and aparently we have cheep doors because they are only 35mm thick haha

Its a simple easy design which makes it so great.

Leaves plenty of room for fingers to remain un-pinched!

It simply pressure fits to the door so its easy to take on and off. Theres a full circle and a lower profile one also.

This is to be printed in TPU or simlar flexible filament.

I have a profile for a 0.6mm and one for a 0.4mm nozzle, but Ive never printed the 0.4mm profile as I used the 0.6mm just to make it a little quicker.

Hope this can help someone!
