Disk Detainer Padlock

thingiverse

Check out my Youtube video for assembly! *WARNING* This model is incredibly difficult to print and assemble https://youtu.be/52WRVL3s14s This was a fun design project that took inspiration from locks in the real world. While disk detainer locks aren't incredibly common, they have picked up momentum due to their rugged design. I hope my design helps others appreciate the intricate simplicity of the mundane objects we see around us every day! Parts needed: 1x Body 1x Core 1x Actuator 1x Sidebar 1x Top Cover 1x Shackle & Ball Bearings 10x Disks 9x Spacers 1x Key Disks and spacers have incredibly tight Z tolerances. They must be 1.6mm for disks and 0.5mm for spacers +/-0.05mm. Disks are numbered 0-3 and have an fdisk variant. Fdisks have false gates in them, which is an anti-pick feature. They make no difference to normal operation and can be substituted for normal disks. You will need 10 disks corresponding to whatever key you have chosen. The sample key requires 2x disk0, 2x disk1, 3x disk2 and 3x disk3. The key will require a bit of filing/sanding to get it working properly. File the EDGES, not the FACES and reference back to your assembled core to ensure the key rotates the disks properly. I have an Openscad key generator as well to generate your own keys! Keycut0-3 and keybow stl's are for use by the program and should be put in a separate folder to be referenced by the generator. Instructions on how to use the program are listed in the code, commented out.
