Key Grip - Helper to open the door

I designed this "Key Grip" for my children. It was too difficult for them to open the door on their own with their key. By widening the grip and adding a textured surface, they can now do it with ease. Especially in emergency situations, this is a very helpful tool. It can also be very useful for adults with disabilities or older people who may lack the necessary strength.

Example: Cutted View with wedges for round keys

Additionally, the grip looks nice and can be printed in various colors to help quickly identify the key. Unfortunately, there are many different types of front door keys. For now, I’ve designed grips for three different types of front door keys. I’ve also made it possible to create your own custom "Key Grips" using a modifier in the slicer.

  • Helps weaker Persons to open the door
  • Diamond surface with super grip 
  • print your grips in different colors to identify the correct key
  • Through the hole in the design the grip can't fall apart
  • Different sizes and option to make your own size
Sizes:
  • Rectangle Width 25mm - Thickness 2,6mm
  • Round Width 24mm - Thickness 2,2mm
  • Round Width 25,3mm Thickness 2,7mm
  • BLANK with Subtract Modifier in the Print Profile

Tips for BLANK with Subtract Modifier in the print profile:

 

Click on object and than on “BLANK” 

to move the Grip out of the way.

Click on object and scale the “subtract objects” first in X/Y for your Key form than adjust Z for the thickness. (Deactivate uniform scale). 

If you're happy with the modifier, simple hit center on the BLANK “Grip”.

Check if  the hole is at a good position. Maybe you have to move  the cylinder slightly in Z direction

 

Happy Printing!😊👍
