Hello Everyone!

I desgined this cardbord box lock for all those planning to move soon and don't want to buy some tape. I am using this to close my boxes since I'm moving soon and it works great. So far this version will only be recommended for the top, I will be designing one for the bottom soon! 
Remember to print 2 to close your boxes. If the box is squared then you can use only one.

Update:

I have added a new part to increase the security of the box and making sure flaps wont open during moving! Refer to print profiles for each part for descriptions. Use this parts instead of tape, they are very useful and easy to print and install

Steps to use:

1. First put both locks on one side of the longer flap (Shown on the picture)

1. Now close both longer flaps into the locks (Shown on the picture)

1. slide the lock out on both sides so it catches the small flaps (Shown on the picture)
