My new 16" f/4.5 project

I have recently acquired complete optics from Meade Starfinder 16" f4.5 and I am planning to bulid a lightweight truss scope, something resembling new Ultra Compact Obsessions.

Here are the planned dimensions:

Altitude bearing diameter: 32"
Azimuth bearing diameter: 20"
UTA: 22" OD, 19" ID
Spider vanes: two sections of 36" diameter ring.
Baltic birch 0.75"
8 aluminum truss tubes 0.75" OD
Mirror face to the focuser hole" 58"
Height of the focuser when pointed at zenith: ~70" (5'8")

I attached few screenshots of my FreeCAD model.

Any suggestions are more than welcomed!
