You will need to print:
1x 3D printed part "MS_mainBody_1.3mf"
1x 3D printed part "MS_mainBody_2.3mf"
4x 3D printed part "MS_cone"
2x 3D printed part "MS_magnet"
(please reffer to "Print_orientation" picture to see how it should be printed, layer height can be .2mm or even .28mm)

2x round magnet 8mm x 3mm (should work with thinner magnets as well but I haven't try it)
1pcs of fine string - around 50-60cm (20-24inch)

Instructions:

1. When printing the magnet parts, make sure to setup your pause/filament change so you are able to insert the magnet. ! Be careful with the magnet poles !

2. How to connect the string is shown in one of the pictures - make sure both sides are equal (for the best effect).

3. Practise... When you disconnect the magnets inside, you have to "reset" it by pushing one string inside and make the magnets connect again.

4. Amaze and have fun!

5. Please share your experience :)
