Electric Lock

a good working printed electric lock

Step 1: Design

after a lot of shapes in tinkercad i made this

Step 2: Print It

print the .stl files (modify the parts for solenoids and shaft if needed)

Step 3: Parts

my solenoids are 16mm diammeter and 20mm height. the shaft is 6mm diammeter the parts are from an old laser printer

Step 4: Glue Them

glue those items with epoxy glue

Step 5: Shaft

add the shaft,a spring like the pics, then add those cylinder items to the shaft (glue them with instant glue if needed)

Step 6: The Other Shaft

modify this part for your shaft if needed

Step 7: Lock-unlock

connect those parts together with some screws (this must can move easily)

Step 8: The Other Spring

add like the pics the part for the other spring

Step 9: Diodes

add diodes to the coils to protect your control circuit

Step 10: End

its ready this work with 24v dc.

hi!! i like tinkercad because is very simple, and i dont know how to use autocad or something like this...

the sollenoids are from an old big laser printer you can find lots of them or like them in laser printers, but are working at 24v DC. I would prefer 12v but those i found

Very nice design and I love that you did it in TinkerCAD. I use it all the time!

Where did you get your coils or did you make them?

Very well thought. My only reserve concerns the use of the soldering iron, it's not a drill !

[andreash79]

yes the right is a drill... WE MUST NOT BREATHING THE SMOKE OF THE BURNING PLASTICS
