Magnetic Toy Building Blocks

Magnetic toy building blocks. Each block contains several magnets to allow different blocks to connect together. All magnets can spin freely inside the blocks so every side can connect to all other blocks.

Edge length of a basic cube is 42 mm.

Design & Printing Details

I printed my models using the following settings:

• Printer: Prusa MK4S

• HF0.4 Nozzle

• 0.2mm Layer height

• 5 % Infill (gyroid)

• No Brim, No Supports

• Pause each print 3 times to insert magnets. Best position is 1 layer before closing the boxes for the magnets

Notice: I only printed 3 models with good distance in a single row on the X-axis, because when printing more rows I sometimes had magnets jumping out and ruining the print. (Probably due to vibration?)

Magnets

I made the design in a way that standard 5mm magnet cubes can be used. This allows the use of cheap magnets like these: https://www.amazon.de/dp/B0CBPQFFBH

Reference

I recently played around with Geomag MagiCubes and found the product really inspiring. Unfortunately the magnets of the original were a little weak, so I thought to design my own compatible elements.
