Summary This is just a little fridge magnet thingy. I was annoyed that my fridge kept getting scratched up by bare magnets, so I jumped into FreeCAD [is that my catchphrase now?] and designed a Thing.
It is designed to hold 8x2mm neodymium magnets but can be customized to fit your particular needs.
Obviously, some assembly required.
The FreeCAD files are included for y'all to customize!
Print Settings
- Rafts: No
- Supports: No
- Resolution: 0.10-0.15
- Infill: 100%
Notes: As with most of my prints, there's nothing magic here. Just make sure to use a lower layer height because anything over .15 will cause the alignment peg on the cap to not print.
All-told, these come to about .45g of filament per unit.
Post-Printing To assemble, the easiest way is to put a magnet into the cup, then tick a magnet to the bottom as a stabilizer.
Spread a small amount of CA glue on the rim of the cup then set the cap on.
Carefully stick a magnet on top of the lid to clamp it down.
To keep all the magnets aligned to the same polarity, use the one you just assembled as the stabilizer magnet to the next assembly.
Repeat ad nauseum.
If the magnet still rattles around inside the little enclosure, you did it right! If it doesn't rattle, you still did it right.
