Introduction: Two Point Door Lock
lets make a strong two point lock
we need
- 3d printer
- epoxic glue
- instant glue
- 3mm shaft
- 12mm shaft
- geared motor
- 2 releys
- 2 terminal switches
- dc to dc step down converter (if needed to slow down the motor)
- input signal (i use motorbike alarm system (because of the control's code))
Step 1: Printed Parts
print the .stl file
you may modify the motor's holder
Attachments
Step 2: Instant Glue 1
glue the 3mm shaft for the central gear
Step 3: Instant Glue 2
- glue the lock's holders if needed
- press it well
Step 4: Mark the Shafts
mark the shafts to glue them with the 3d printed parts
Step 5: Strong Hold
- cut a little the 12mm shafts for a strong holding
- glue with the epoxy shaft and 3d printed parts
Step 6: Assembe
- add the 12mm shafts on the lock-door
- assemble all the parts
Step 7: Make H-bridge With Terminal Swiches
make a simple h-bridge with 2 relays
that must have
- 2 inputs for relays
- 2 inputs for terminal switches
- dc input
- output to motor
Step 8:
add the motor and conect the wires
Step 9: Lock-unlock Distance
add the terminal switches like the pics (i use instant glue)
glue them at the corect point for the lock-unlock distance
Step 10: Thanks and Good Luck!
if it broken good luck!!
you must always have a plan b to get in
