The bug

From the brewing stand's introduction up to 1.7.10, each of the brewing stand's arms were rotated 120 degrees from each other, resulting in each arm being at an identical angle from the other two. However, in 1.8, likely due to incorrect model conversion, the angles of these arms have changed to two 135-degree angles and one 90-degree angle.

How to reproduce

1. Place a brewing stand
2. Analyze the three angles between each arm

Expected results

The three angles would be roughly the same.

Actual results

In versions 1.8 onwards, one of the angles is noticeably different from the other two.
