I designed this compass because I couldn't find one that i liked. Straight forward printing, easy to assemble.
This compass will draw a circle 23 1/2" in diameter.
number 6 machine screw
number 6 machine nut
3- 1/4-20 nuts
2- 1/4" flat washers
After printing, remove brim.
Locate handle parts A and B.
Snap 1/4-20 nut in to handle part a
Put glue inside handle part B and push handle part A nut first in the hole. (this will capture the nut)
Cut 1/4-20 allthread to approx 3" in length and use file or grinder to sharpen one end
Assemble the rest of the compass using pictures as a guide.
