Hi,
This model expands on https://www.printables.com/model/437061-rollup-dice-box-tower-core. I printed the tower some time ago but always found the small hole in the top annoying while playing, especially while throwing multiple dice at once. As I didn't really find anything available that would work for me I hopped into Fusion 360 and designed my own funnel.
I remixed the threaded cap and put a funnel on top of it so you don't have to be as precise and can easily throw in multiple dice at once. I printed it in PLA with only 2 perimeters and 2 top/bottom layers and 5% infill because I needed it fast but it held up great through the first play test.
I will probably make a V2 as there are some problems/improvements I would like to make so check back for that if you're interested. Problems I have found is that d6 tend to get stuck (you can easily push them through though, other dice seem to work OK so far) and it's a bit bulky to take with you. Let me know if there are any other improvements you would like to see.
Have fun rolling!

I took the original threaded cap and remixed it to have a funnel on top
