Lock and Lock Holder

My first Upload to here, i hope you like it!

How I mounted it:

To mount it to the ceiling i first drilled two small pilot holes with a #2 wood Drill Bit to thread the screws into. Then, while firmly pressing it to the ceiling i used long screws that can bare the Weight of my filled containers and screwed them directly to the joist.

Recommendations: 

Use a high amount of outer and bottom layers if planned to fill with heavy items to ensure it wont bent overtime.

I used black ABS for the fuller one, but PLA is holding up the other ones just fine so far and is not showing signs of failure. 

Make sure to have plenty of space to the wall to allow the free turning of the containers.

Lastly, check to have a good amount of tolerance otherwise the top container will get stuck and not come loose.

Have Fun :D
