Magnetic key hiding box with sliding lid

Magnetic box with sliding lid - used to hide keys under car

Materials:

4 neo-dymimium magnets 9mm x 2mm

I designed this box with 4 holes in the bottom so 9mm magnets can be glued in, making a box that can be stuck on the underside of a car.

I couldn't be bothered buying a key lock for when I go surfing or visit a swimming hole so decided to print a black box with a sliding lid to stick under my car (I used to just sit my keys in the suspension of my car). I figured this is a little more security conscious.

Print Settings

Printer:

Cocoon create

Rafts: 

No

Supports:

No

Resolution: 

0.25mm

Infill:

20%

Notes:

I put supports in the first print and it turned out average. Removed supports on the second print and came out beautifully.
Using a cocoon create (Wanhao i3) with a 50mm blower fan upgrade I could bridge these gaps with no dramas.

!!!!In your slicer, make sure you split objects as the box is a few mm higher than the lid for some reason. Splitting levels them onto the print bed in your slicer!!!!

Post-Printing

After printing I sanded the tongues that slide into the box a little. It was too perfect a fit, and I wanted it to slide a little better even though I had a decent tolerance in production.

Just use some wet and dry sand paper and give it a quick sand. Slides nicely.
