Retraction Test

Update 09/12/16: Modified the shape of the base so you can tell left to right once you take them off the bed.

Designed these to test retraction. Cylinders are 100 mm apart.

Print with 0.4 mm bottom layer, no top layers, 1 wall, 0% infill. You can also set the Z seam to be at the back so you can inspect them.
