Save Storage Space!

This project can help you save space in your refrigerator! A 3D printed strip holds a series of rare earth magnets that are strong enough to hold different types of containers.

The 3D printed strip features three groves where 1/2" diameter sized magnents can snap fit into. The strip is then mounted to the top inside of your refrigerator with double-sided foam tape.

Modify and Remix!

The strip has three spots for a set of four magnets, which can hold up to three different containers - But you can tweak the design to make it longer!

Parts

You only need a handfull of magnets, some double-sided foam tape and a 3D printer to make this project.

• 12x Magnets
• 3D Printing Filament

Tools and Supplies

• 3D Printer
• Hobby Knife
• Foam Tape

3D Printed Part

The strip holds the magnets in place by press fitting them into the groves. 

Slicer Settings

To slice the strip part, we used Simplify3D. We recommend using the settings below or use them as reference. We 3D printed the part on a Ultimaker 2+ with a 8.mm nozzle. If you have Simplify3D, you can download our profiles below.

Customize The Design

The parts where designed in Autodesk Fusion 360. The design is public and available to download in different formats. If you'd like to use a different CAD software package, you are free to import the files and remix them.

Resizing Magnet slots

If you need to add or remove magnets, you can edit the slots on the strip by editing the sketches.  

Editing pattern

The pattern and spacing for the slots are adjustable by editing settings in the timeline.

Resizing strip

The length of the strip is adjustable by editing the sketch dimensions in the timeline.

Filament Materials

We recommend using PLA material to reduce wrapping while 3D printing. The parts can be printed in different types of filament, such as ABS, PET or Nylon.

Tolerances

The slots for the magnets were designed for .4mm nozzles, so they may have different tolerances depending on your printer. Test the tolerances by printing a test with a single groove and inserting the magnets. If the magnets don't fit into the slots, you may need to use a craft knife or filing tool to loosen the area. If it's too lose, you can use E6000 adhesives to perminently hold the magents in place.

Assembly

Start by arranging four magnets in a square, then press fit them into the groves.

Save Space!

And that’s it, your fridge will be more spacious.

Whether you need space for leftovers or you just like to keep your fridge tidy, this simple project is a great use of 3D printing!
