Changed
Import the original STL files into blend file.
Move parts to the center (they were around 5500).
Rotate the arm to print with less support material.
Move the tab inward by 9mm so it actually goes into the slot.
Add a ridge for matching the compass to an edge.
Face the letters down for printing the body without supports.
The "top" is now the flat side, such as in the naming of the blend
file's vertex groups.
Reduce the thickness of the body from 8mm to 3mm.
Include a 4.8mm axle and make the hole in the body 5mm for it (a bolt is no longer required).
Add a 2mm hole to the new axle for an optional panhead screw.
Make the tap narrower for less drag.
Half the thickness of the arm so that it is useful for finding the center.
Reduce the body's plastic usage to 564.81cm = 13.59cm^3 = 16.85g (from 943.52cm = 22.69cm^3 = 28.14g)
(at 4 perimeters, 4 solid top & bottom layers, .32 layer height, 20%
gyroid infill)
Add holes to save material.
Make the straight edge thinner.
Make the arm printable on its top (upside-down) by making the tab have
a 45 degree angle.
Make the body have a 45 degree lip to match the arm's new tab.
The arm can print without supports on its back.
