Same sizes as a popular giant stomping mech game.

READ THIS BEFORE PRINTING:

There's a trick to printing these quickly (in Cura at least) with the following steps:

1. Flip the model upside down.
2. Set "Shell" / "Top Layers" to 0. This is very important.
3. Set "Shell" / "Bottom Layers" so a value so that the final thickness will be around 0.8mm - my layer height is 0.08 and I set this value to 10 so that the total thickness is 0.8mm.
4. Set "Infill" / "Infill Density" to 0.
5. For a 0.4mm nozzle, set the "Shell" / "Wall Line Count" to around 3, maybe 4. Use more with smaller nozzles. I use a 0.25mm nozzle and my wall line count is set to 5 which may be a bit thin.
6. Disabled "Shell" / "Enable Ironing" if you have it on.

I'd advice creating a new profile and saving it so you don't mess up your existing one.

This should give you a hollow hex base with no bottom on it that looks a lot like the "real thing". You can print them quick and they don't use too much filament. With the rest of my settings on my Ender 3, they take just over 20 minutes each using about 1g of filament. Don't make them too thin or they'll potentially warp.

I assume other slices have equivalent steps.
