Zylmex/Zee Dyna Flights Airplane Replacement Wheels With Configurable Files Included!

There's two main versions here. You have the single piece in .stl and the .blend, which is true to what I measured, and another version with just the wheel and no axle so you could print it in 2 pieces and join with a wire which is better than a fully printed part since it's so small. The measured axle is 1.2mm but I included a few variants with other tolerances for the axle which is what the +.Xmm refers to with 1mm being the assumed precise intended measurement but the true file is what I measured and personally would start with. I'm also including my .blend file in case you need something different or want to make more detailed wheels. Just size the top/bottom, post and optionally a Boolean for custom split wheels and tolerances via Boolean modifier.

Hope it Helps!
