Note: The model file is slightly different from the picture, I've made a few adjustments that should make assembly a little easier.

This is my first ever 3D model! I wanted to try making a different version of the flight risers I've seen, and this is what I came up with.

It's pretty simple, you just spin the ring to indicate what height the mini is at (the lines are to indicate 5 feet increments).

I've tweaked it a few times to make for a better fit after printing, but let me know if you have any difficulties, and I'll see about adjusting things.
