Noticed a lack of fun springy door stops, wanted to create my own with a modern fun look. Printed in PETG this model provides enough force to gently stop the door preventing a slam. 

The “Spring” measures roughly 90mm when compressed when mounted to trim this provides plenty of distance between the wall and the door knob. Depending on your door knob you may need to stretch it in the slicer. The mounting system shouldn't be too effected by doing this. 

Mounting is easy with a single #6 Wood screw, screw in the screw to a similar depth showed in the photo. 

The TPU Bumper fits well as a friction fit, some glue may be applied to affix it permanently but this is not necessary.
