Thin Iris Drawing Compass V1 (Go Check out V2!)

V2 is out now! (It has fixes for a better fit)

It's an adjustable compass for drawing that uses an iris mechanism. The design is my own, but I took inspiration from the following iris compass linked below. My design is quite a bit thinner, although it may not produce the most precise circles.

Important:

• The compass may initially have a lot of friction (especially for matte filaments). With more use, friction decreases a tad. Ironing can be enabled for top surfaces which helps to eliminate friction. I added a little bit of lubrication fluid I had laying around from Hub Hobby to the flange of the top before assembly, which helped a great deal.

Assembly:

• Carefully use a scraper to remove the thin parts from the build plate.
• Place the Base on a flat surface.
• Hook one Shutter at a time over an outer peg of the Base. Work in a clockwise manner. When installing the last 4-5 Shutters, you will need to slide them under the first few initial Shutters while holding them in place and hook them over the pegs. A photo of all of the Shutters installed on the Base is provided.
• Run your finger or something around the inner edge of the Base to align all of the Shutters.
• Rotate the Base assembly so that the slot on the edge faces you.
• Take the Top and lay it on top of the Base assembly so that the protruding nub is in the left edge of the Base slot.
• Shift the Top so that all of the Shutter pins are aligned with the Top slots.
• Push down on one edge of the Top with one finger and slide another finger around the edge of the top until it is attached to the Base.
