Introduction

As a recognized home childcare provider (and long time early childhood educator) I must insure that no household cleaning products are in children's reach…but at the same time, I must use them very often.

So this project was born from the desire to make such products easily accessible yet out of reach of those tiny hands.

Note : I use it as storage for a small spray bottle…but it could be used to store other things, like first aid stuff…

 

Safety warnings

This device is child RESISTANT, not childPROOF (nothing can be truly childproof) thus it cannot completely replace adult surveillance/supervision. This is a DIY project and its performance will mostly depend of your hability to print and assemble it correctly. Use at your own risk.

Safety tips
  • After printing and assembly, check with reasonable force if everything is solid and if the storage compatment is hard to open ;
  • Place the device at a height that makes it hard or impossible for children to reach. especially younger ones ;
  • Print everyting in a non-attractive color, the same as the wall (if you are installing it on a wall) if possible ;
  • Still instruct children not to try to temper with this device. Don't try to hide its existence…they will see you use it sooner or later and it will spark more curiosity ;
  • Also read and follow your magnetic lock user's guide.
Printing instructions

All objects prints without support but I suggest using a brim to prevent warping and be sure that the hooks from the casing don't fail during print.

Note : if you use a brim, it may be possible that you have to rotate the casing to make it fit on a smaller bed (ex: Prusa Mini)

Beyond that its up to you (material used, infill density, number of walls…). Personnaly, the standard .2 [QUALITY] profile in PrusaSlicer fitted my needs (2 walls, 15% gyroid infill).

I used modifiers to make the area where a screw would be used to be at 100% infill but I did'nt like the result. If you want more rigidity in those places I suggest printing with more perimeter/walls instead. Still, I joined a .3MF file to open in PrusaSlicer with the modifiers already made, if you ever want to try….

I also included .obj files so you can resize/modify the design with your favorite 3d editing software. Finnaly, the original Blender (.blend) file is included.

 

What you will need

1- 3d printed parts ;

2- A magnetic lock (for this project I used the HS132 from Safety First… but others could fit) ;

3- A 3/16" steel rod (and the tool necessary to cut it) ;

4- Plastic glue (if you want to use the caps) ;

5- A spray bottle that fit (I used a small “travel” bottle with a spray nozzle took from another one). The model was made to accomodate minimaly these dimensions : X=50mm, Y=110mm, Z=165mm

 

Assembly

General tip : don't over-thighten any screw !

 

Step 1

Print the parts needed (the casing, the door and the caps if you want them).

 

Step 2

Install the main magnet lock on the door.

 
Step 3

Install the second part of the magnet lock on the casing.

 

Step 4

Join the casing and door with the steel rod (cutted and the correct lenght). Verify that everything fits and work as intended. Note : if you want to use the caps, the rod must not protrude from the casing.

 

Step 5

Remove the door and fix the casing on a wall or other out-of-children-reach surface. Check that everything is solid.

 

Step 6

Replace the door and steel rod. Put caps over the holes where the rod goes (optionnal). If you use the caps, apply a little bit of plastic glue/superglue… if you ever need to remove the door without using the magnetic lock, simply use a flat screwdriver and a little tap to remove the caps and after that the steel rod, thus releasing the door.
