Fully 3D Printed Combination Lock

This is a fully 3d printed combination lock. It is quite strong and can be used outside if printed in PETG. I have included 3 print profiles, regular, AMS, and strong. The AMS print profile prints the numbers in a different color while the strong print profile uses more perimeters and higher infill. To use the lock you just set the correct code and pull the shaft from the bottom.To set the code you align the number that you would like to the notch on the inside wheel. To assemble the rest of the lock first you insert the middle slider into the core ensuring the side with extra space is going through the bottom. Next you must slide the bottom ring onto the core assembly with the flat ring side facing out. Repeat this with the other 2 rings making sure it looks like this. The last step is to just push the top with the lock onto the main assembly. This connection is a press fit with the hook side having a slight taper. I personally would put a little glue on the inside of this connection
