v4.6.0

Features

• All frame pieces were updated to have flush edges, a la the "extended" sides, rather than the seam between the front/back and the sides being at a 45 degree angle on some pieces, with the latter meaning that we were maintaining two (complicated) duplicates of the same pieces because both 45 degree and 90 degree angles were necessary. This does not affect the look of the build much, but simplifies the print and the maintenance of the project.
• A slightly-extended flat side piece was added, to add just a bit of length to the overall build.

Improvements

• One more slash has been added to the frame pieces, just for more interesting visuals.
• The rectangle plates' positioning was tweaked slightly.

Fixes

• The frame solid was very slightly shorter than it should have been as the corners relied on cylinders. The core solid is now at its proper dimensions.
