The file 'Inkwell 3D Printer Model' is (stl) file type, size is 584.9KB.
UPDATE 04/10/2020: Changed inner cavity profile to be conical at the bottom so that ink can be used to the very last drop (credit goes to reddit.com/user/AllTheWine05 for suggestion)
A simple inkwell that can hold about 4.7 ml of ink. It has a droplet-shaped cavity for ink so that it doesn't get stuck in corners. Also there's a shallow cutout across top surface for resting the pen on it or draining the ink (thanks to the radius on the inside and sharp outside corner).
