Magnetic Lock Pencil Case

thingiverse

I've recently been focusing on putting the practical applications of 3D printing into action, and after a string of unsuccessful attempts at making a pencil case I finally came up with something worth sharing. It's based loosely on a Reuleaux triangle, but I added fillets to make it easier to hold onto. It doesn't matter what infill percentage or layer height you use, but supports are pretty much essential and you may or may not need to use a raft depending on how the pattern at the base turns out. Different surfaces could produce different finishes, so since I own a Cetus, I basically had to use one. The locking mechanism requires six 5x5mm cylindrical magnets, and I used Neodymium ones that can be held in with plain superglue, though you might have to be careful while pouring it into the holes. The model in the pictures is printed in two different materials since I forgot to switch them around (well, that was a mistake). I might try making a parametric version or even a modular one at some point. In total, at 20% infill it took about 100g of filament. Excuse my bad photography skills, but I hope you enjoy this!
