How it works. Each chute is a column just wider than a daily blister, so a month's worth stacks flat inside; the floor slopes toward the front, and the bottom blister rests at the window where you take it. The window is arched and the top is open, so it prints upright in one piece with no supports. Standard blisters fit Acuvue, Dailies, Biofinity and most others; pick Wide for the bigger foil packs.
On the wall or the counter. Two keyholes on the back, behind the sloped floors where the body is solid, take two screws or nails. On the counter the plinth stands it, with a small lip at the front. PLA, 2.4 mm walls; wipe with a damp cloth.
