I'm using a piece of 2.25 inch OD acrylic pipe or tubing -
I sits about about 3 inches out of the collar - I'm just holding it in with the screw that holds the mazzer bin in place.
I was given the piece of acrylic - so just kind of made it work. I wanted something taller, this is working out better than something taller would have.
A tamper was too heavy, according to my calculations. Turns out that an empty pill bottle, with a few quarters in it bringing the total weight of pill bottle with the quarters inside to 80 grams is equivalent to a large hopper filled halfway up ( after taking into consideration the five doubles in the pipeline - which includes the chamber).
Why it is working so well for me is I can easily track and keep up with how many doubles are in the pipe.
there are two doubles below the collar and three above. I just pick the pill bottle up and fill the tube each shot.
So, I take what I think will be tomorrow's shots out of the freezer and they should be correctly aged.
If you can see the thin gray lines - they are simply made from adhesive labels cut thinly and placed a double apart.
I can judge very closely how much to grind visually by simply eyeballing how close I am to the top line when I start and shut the grinder off when I get equally close to the bottom line - have to anticipate slightly because there's a slight delay while the burrs spin. I'm getting pretty good at it

In the pic, the acrylic is clear and the prescription bottle is somewhat orange looking
