Thank you Irpetey for including the .ipt files for your awesome dice tower!

I rebuilt the fence for the dice so there's more room for them to roll as well as making it printable in pieces, and all at full scale. I also added an alternate version with a peaked door that requires less support and some may prefer aesthetically.

UPDATE 2020: Larger holes to ensure dice still fit when scaled down, better split parts with assembly holes, slightly larger upper ramp, and redid the ALT version's peaked door.

The tower is 490mm/19.3 inches tall, and the base and wall are 265mm/10.4 inches deep. If you have a smaller printer or if that's too big for your table, 70% scale will make it 343mm/13.5 inches tall and 185.5mm or 7.3 inches deep, and the dice hole will still be more than large enough for standard 16mm d20s.

The Fence is 160mm diameter and the Top is 173mm tall. If that won't fit on your printer 70% will make the Fence 120mm wide and the Top 121mm tall, and if you're fine with printing for 2 days straight you could fit everything on a 220mm build plate at that scale.

Thanks to CorujaCork for the first make, I made the holes much larger after he pointed out dice didn't quite fit the original holes at 70% scale.

Thanks to gdalya for the first full size make, I altered the points where the model is split so they're similar heights and will fit on a Prusa Mini at full scale, and added holes that can be used with 1.75mm filament as assembly guides.
