Improved Base of Collapsible Dice Tower

(copied from the original upload at https://www.thingiverse.com/thing:5255042)

Summary

All credit to aclugston for his great dice tower! I used the original for months on my desk while online gaming, but dice always got caught in the opening at the base. I improved it by stretching the base up a little and extending the ramp to closer to the opening. Now dice don't get caught and more can be rolled out consistently.

It still collapses fine when attached to the original tower segments. Bonus is that with the increased base height, more dice can be stored in the tower when it is collapsed.

This base will still connect to the original pieces of the tower. I just print this base out to upgrade the existing towers I have printed.

Note: this update is based on the thick-walled version of the tower.
