I’ve put a lot of time and effort into designing this lock from scratch. If you are able, I’d really appreciate a boost to help it reach more makers. Thank you!
Description:
When I set out to find a fully 3D-printable tumbler lock for learning purposes, I realized there wasn’t anything quite like what I had in mind. So, I decided to design one myself! This lock is a functional 6-pin tumbler lock that requires a key to open, just like a real padlock. It’s been carefully optimized to work well with 3D printing, making it both an educational tool, functional, and a fun project for makers.
Key Features:
- No Extra Hardware Required: This padlock is entirely 3D printed—no screws, springs, glue, or additional parts needed
- Compact Design: Lightweight yet robust enough for light-duty applications
- Fully Tested: The locking mechanism has been refined to ensure reliable operation
Assembly Instructions
- Print all the pieces
- Insert key pins into the tumbler
- Putting the key in the keyhole helps identify where all the pens go
- The tops of the pins should be level with the surface of the tumbler when assembled properly
- The orientation of these pins also matters, it should be oriented so that the rounded surface is on top and matches the curvature of the tumbler
- Insert the tumbler into the barrel
- There is only one way that it fits due to the chamfer
- make sure that the pin holes are lined up
- Insert the driver pins in the barrel
- Orientation does not matter
- Insert the springs
- Use the pin cover to close everything in the barrel
- Put the lock body on a flat surface with the barrel shaped hole facing up
- Put the shackle pins in the bottom of the hole
- These pins go into the holes in the bottom with the rounded end facing out
- they should be pushed as far into each hole as possible
- Insert the barrel with the attached tumbler with the key hole facing out
- It is helpful if you check the lock mechanisms functionality at this point
- It is easiest to insert the barrel when it is in the unlocked position
- Flip the lock over and put the screw in the correct shackle hole
- Use a flat head screwdriver to tighten it
- Make sure to not screw it in too tight
- While the lock is still unlocked, insert the shackle and lock the lock
- ALL DONE!! ENJOY!!
Note that the lock parts may need some cleaning up to function better and that it may need to be operated a few times for smoother operation
