Secret shelf with invisible magnetic lock

Secret shelf with invisible magnetic lock

Once screwed to your wall and the lid pushed onto the base no one should be able to tell that this is a secret shelf where you can hide little things in.

The inside is about 125x125x50mm so a lot of room to secure some smaller things you want to hide.

The lock is based on 3 round Ø6.35x25.4mm during print added magnets that are inserted into Ø7.5mm holes that connect the “Lid” part strongly to the “Base” part. The case can be opened and closed only when you are aware that you need 3 additional magnets to pull the inserted 3 magnets to the top and release them into the lock once the lid was pushed onto the base again.

Parts needed: 

• 6 round magnets Ø6.35mm x 25.4mm 
• 2 screws Ø6mm x 40mm to screw the “Base” part to your wall.

Printing instructions:

• 0.3 draft profile used
• Supports required from the print bed
• No brim required
• Wall perimeters set to 5 make the parts more stable
• For the “Lid” part a color change has to be added at about 45mm height to add the magnets in the correct orientation into the already printed holes for the magnets. The magnets cannot be added after the print to avoid them from falling out of the print. Therefore the color change was added to stop the print, add the 3 magnets and then continue the print with the same color that was used before…
• Check the orientation of the magnets before adding them so that you later can use the 3 other magnets to pull the inserted 3 magnets to the top to open the lock…

Happy printing =)
