This is a remix of a model made by Kezat. I made it longer, put accurate millimeter and imperial measuring marks on it, made the tightening knob larger and reduced clearances for moving pieces for more accurate drawing.

• After printing, if the pen tip holder ‘shuttle’ doesn’t slide along the compass ‘rail’ guide, hold each end of the guide and very gently slightly twist either end in opposite directions. the shuttle should then slide freely. 

• Insert small clips as shown in photo, screw nut onto the tightening thread, insert sharpie and draw circles :D  

Original details

"Tool to create perfect circles that also functions as a ruler, millimeter and inches. Curved end has degree marks every 10 deg.

The tolerances are somewhat tight and it will need a well tuned printer."
