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.


235c extruder
50mm/s print speed
120mm/s travel speed
0.8mm Nozzle
.96mm Extrusion width


Lay the strip flat so the slots are on top. No supports required.

The strip doesn't require any detail, so we used a .8mm nozzle to speed up print time to one hour.

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.


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.
