Blood Red Skies bomber stands, rulers and turning calipers

Slightly larger versions of my Blood Red Skies stands (45mm diameter rather than 39mm) along with turning calipers and a 6-inch ruler with curved edges modified to fit the slightly larger stand.

These stands give a bit more stability for the larger bomber models but still take 8mm dice as for the standard (39mm) stands (https://www.thingiverse.com/thing:6528268). The stands still fit the standard Warlord triangular hole so can be used interchangeably with either the warlord stands or other 3D printed stands such as my own 39mm stands or from ElBananito

Remixed from various people's work (should all be shown below) with various additions of my own.
