Countertop Coffee Dispenser (also great for sugar/whey/psyllium)

This is a countertop or wall-mountable dispenser for coffee grounds that I originally designed specifically for refilling reusable k-cup pods at work. However, after going through many revisions and tuning the function, it worked so well that I made three more for myself at home. 

The vitamins (non-printed parts) for this dispenser are:

1x Zevro/HoneyCanDo 34 ounce dry cereal dispenser (though other 85mm OD tubes will work): https://www.amazon.com/gp/aw/d/B00ANJDBWM

4x MR115 bearings (though any bearing with around a 4mm ID and less than a 12mm OD will work, I just had these on hand from a Trad Rack build): https://www.amazon.com/gp/aw/d/B08531G3GT

5x (minimum) M3 heat set inserts: https://www.amazon.com/gp/aw/d/B09MCWTBCC

3x (minimum) M3x8-M3x12 (variability is built into the design) bolts

2x M4x20 bolts

1x 6 inch/150mm “heavy duty” rubber band (I used these 8 inch bands I had on hand, and tied a knot into it to shorten it): https://www.amazon.com/gp/aw/d/B08B83NJXH

The .STEP file can be imported directly into Prusaslicer and split into objects. I include a STEP file to show how the object is assembled. The scoop, shuttle, and optional hook for the shuttle are separate files. 

The side of the scoop is sized as a tamper for refillable k-cups.
