Mechanical Pencil Holder

This is a hard case I designed for my mechanical pencils. It holds 2 pencils, refill erasers, refill lead, a 6" ruler (mine is a cheap plastic one.) and a hi-polymer eraser block. I measured this off or Pentel's Graphgear 1000 mechanical pencil set.

This design has a hinge that uses a simple paper clip as the joining rod. There is also 4 spots on the body and lid for 3x2mm magnets to help hold the lid close. Tolerances are a little tight, but once finagled together I am pleased with the outcome. You should be fine with printing this without supports. my mistake was with supports and basically made it hell installing the paper clip.
