Keyholder Keyhole Key Holder Lock Closer Room Internal Door Schlüsselhalter Schlüsseltürhalter

Hey :)

i designed a little key holder for internal room doors. So the key doesn't fall out of the lock.

It also reduces the noise coming from the other side of the door.

I printed it in TPU 95A.

My keyholes have this size:
widht: 8.5mm
high: 15.5mm

I added a Keyholeholder with a little hole to see if there is light or not on the opposite of the door. And i added a Keyholecloser to close the Keyhole on the opposite of the door. With and without hole.

TPU or TPE is not easy to print for beginners. Use the right settings in your slicer or use the preconfigured 3mf file ;)

Also very important is:

Release the pressure from the retraction of the filament (bondtech gears)
Increase the nozzle temp if you encounter issues (235C is just perfect)
No retractions!
Print with slow speed! 20-40mm/s
If you have problems with the filament sensor, deactivate it.
