UPDATE: Chamfered the compartment edges as they were REALLY sharp.
An over engineered pencil case, the top section is its own compartment to keep a sharpener and eraser separate from the main body. The bottom has its own screw cap, as well as the top. This was an exercise for me in thread creation for Fusion 360, plus I need somewhere to carry my sketching gear. Print standing up, caps should be printed with threads facing UP, same with the top chamber (don't print threads as a base.)
Not much else to say about this one, outer diameter is 35mm, inner main chamber is 30mm (so that should come up to 2.5mm walls). Main part length is 190mm, top chamber is 65mm. You can use this without the top chamber and just attach the top cap.
Here it is in all its glory, use it for personal protection/weapon/running baton/flare case/twirling baton/lipstick case
PRINTER TOLERANCES MUST BE DIALED IN, print at .12 rez in PLA (tested at .2 and was fine) if you want decent threads, plus these are M32x2 so they're pretty forgiving.
Print facing up, theeads facing UP
