As my previous attempt at designing a modular flying base... Less than ideal, I made a few new ones.

Made 2 versions of each size from Medium to Gargantuan. 5 & 10ft elevation. The bases stack on eachother.

They're designed in such a way that the base fits nicely in the top bit, so you can stack them to your heart's delight.

Just updated the Large, Huge & Gargantuan bases to fit with the corresponding land bases I have

Just found out I did an oopsie with the “10”, so corrected that.
