No Spill Travel Inkwell

thingiverse

This is non-spillable travel inkwell: when it's closed, you can put it in your backpack or pocket. When it's open, it's still won't spill if tilted. Use it with water-soluble ink, because cleaning it is a bit difficult. The only unprintable parts is a small screw (any type of thin screw, no longer than 5-7 mm), and o-ring with inner diameter 18.64 mm and thickness of 3.53 mm. I get mine from automotive o-rings set, probably it's pretty standard. Or you can print one in flex plastic, I've included the model for the ring, you'll need to print it “upside down”. The part, named with “_oriented” suffix are the same as without, but they orientation is better suited for printing (it's my opinion, you may print them as you wish). Waterproof inner part of body and funnel part after printing! How to assemble: 1. Put o-ring to the cap 1. Attach cap to funnel part, you may use filament as an axel 1. Press latch into place 1. Glue funnel part with thick epoxy to the body 1. Open cap, glue second part of the hinge 1. Attach cover 1. Adjust latch with cover, screw it with a small screw in place
