I prepared this illustrative model of a lock with a key to understand the function of the door opening and closing mechanism
Vždy ma fascinovali mechanické veci, ako fungujú a na čo slúžia. Zaujímal som sa o Cylindrický zámok na kľúče, especially that such a small thing can protect so many things - your home, property, safety and privacy. So I looked at this mechanical miracle in more detail.
Of course, because of this, I disassembled and damaged one of the original locks.😦
This model is more demanding, especially for the post-processing of parts after printing - removal of supports, which were necessary for some parts, their cleaning, smoothing.
Mainly, the printing layers greatly increase the friction between the parts, so I used a lubricant.
I managed to move my model, I was skeptical at the beginning, but I am satisfied with the results.
I hope it will be successful for you too, I will be very happy
The scale of the model is 2,4:1
The dimensions of the model are 160 X 75 X 41 mm without base.
The key is 124 mm long
I processed the instructions in a video
You will need 10 pieces of 7x35mm springs and 3 pieces of M3x10mm, 1pcs M4x15mm
Connect the Clutch parts A+B with an M4x15mm screw to rotate freely
The spacer goes into a Long Barrel
Just as you insert the key pins in the Long Barrel, mirror them in the Short Barrel, then Middle pins, springs and close with Ends pins
Some parts have supports, I uploaded the G-code with the settings
Important! When pulling out the key, hold the cylinder, it will pull out better
I hope I haven't forgotten anything, if so, please ask. Recording this model has exhausted me, I'm going to rest and gain energy for a new model!
I bought the springs in the OBI supermarket, but I also found another source:
