This model is original from Thingiverse user " ieatacid "

I took the idea and redesigned all parts.
I used larger magnets and adjusted the angle of the magnets.
When the lever is locked with the key, it stays locked, and when it is opened with the key, it stays in the open position.
I designed an assembly tool because it is very difficult to get the positioning right.

Now you can just put the parts in the mounting tool, attach them to the door, pull the string and you're done.

You need 3 types of magnets for this print.

• For the housing you need 1 piece of 10x2mm magnets
• For the lever you need 1 piece of 12x2,5mm magnets
• and for the key you need 2 pieces of 15x5mm magnets

When assembling, make sure that all magnets are oriented correctly.
The magnet from the housing must repel the magnet from the lever.
