Scope Ring Height Testers - 1" tube

This is a requested remix of my [30mm Scope Ring Height Testers](https://www.thingiverse.com/thing:5406437) now for 1" tubes.

These scope rings are modeled after [Vortex Precision Matched Rings
1 Inch](https://vortexoptics.com/vortex-precision-matched-1-inch-rings+vx_ring_height-76~inches~Weaver), and match all the heights they have available (rail top to scope center heights):

* 0.76"

The _split_ring_top.stl file is designed to be printed in a flexible filament, so that scopes can be temporarily press-fit into the rings.

Required hardware:
8x M3x12mm hex head screws to attach ring tops to bases
2x M5x35mm hex head screws to attach bases to picatinny rail
2x M5 hex nuts to attach bases to picatinny rail

\#8x1-1/4 hardware will also work for attaching bases to rail for metric-challenged users.

**Note**: they almost surely won't hold zero in real use, just intended to help determine which height rings to buy.
