Flip open pencil case

Similar design to the old wooden pencil cases where the case pivots open and close and a sliding lid to lock it all in place. Nowadays this is more useful for pens. I imagine its multi-purpose too - I am thinking about putting my 3d bits and pieces in this.

All pieces = No Support Needed
Infill 10% but with "Wall Line Count = 4" recommended so the bolt hole is strong (Its the only advanced setting to change in cura)

Only need 1 x M5 bolt to lock it together (M5 x 30mm) with optional nut.
(I actually only used a M5x24 and because it screws in firmly and taps itself as you screw in, no nut needed)
