K&E 4181-1 Cursor bar

I had a broken part on my Keuffel & Esser pocket slide rule, so I designed this replacement. The reliefs on sides and bottom are slightly larger than the original to allow for printing. Print laying on the side with supports to ensure round holes.
After printing, some sanding/shaping will be necessary to get the three mounting surfaces smooth and at perfect right angles to each other.
The screw holes are sized such that tapping should not be necessary.
