Single Dose Espresso Dispenser v1: 14 and 17 tube

This is version 1 of a dispenser for 50mL centrifuge tubes, which are commonly used for pre-measuring and storing beans for single dose espresso.

Centrifuge tubes from all brands share similar dimensions and this dispenser is designed to work with both conical bottom and skirted ("Self Standing") tubes. They are inexpensive and easy to find at most online retailers.

Placed with their caps in alternating directions, the tubes will gravity feed down to the outlet where they can be used and then placed back in the top of the dispenser until it is time to refill. The tubes are visible from the sides of the dispenser so their orientation is visible and it is always easy to feed them into the dispenser in alternating fashion.

A compact and pleasant to use solution.

Two profiles are included, a short dispenser which holds 14 tubes, and a tall dispenser which holds 17. The tall dispenser is the one in the pictures.

This dispenser can be printed on its side almost entirely without supports, except for a small section on the tube stopper at the bottom of the dispenser which is already painted with supports in the provided profiles.

The provided profiles print with 3 walls, 2 walls can likely be used to consume less filament. I'm just in the habit of printing everything which sees some use as a functional item a little extra strong.
