Please use the above link as the step file I generated this stl from was not the original the original and I found the author, all credit goes to them. The link above is much better!

Remix to be a stl. Could use threads inside the top to screw the glass into and keep attached. Little bit wobbly without anything in the glass jar.

Test printed (see my make) so I know it works. Tolerances are tight, make sure you have tree supports easily detachable before printing or they will get stuck in the top of the exit hole and can be a pain to remove. Also had trouble getting the supports out of the end of the gumball turn thingy.

If you have problems with the tolerances you can use a quick focused heat (from like a small heat gun) on the base and then insert the pins and let cool.
