MicroLongRange_20X20_mod

This is a modification of the [#MicroLongRange ](https://www.thingiverse.com/thing:4054381) frame to allow for a 20x20 center stack. Tested with an omnibus F4 V6 Nano/Ori 25 Amp ESC combo. Arms are identical to the original and have not been included. With the mod, the total frame length increases with 6 mm.
Please see the original frame post for the great in-depth discussion on performance and alternative hardware. All credits to the original design.

Stack medial length must not exceed 30 mm total plus 2 mm on each side to the center standoffs (including esc/fc wires), see illustration. Make sure your fc/esc fits including wires. The 6 mm longer frame is therefore a minimum increase in size to allow for sufficient space for wires.
