The Spinout puzzle

This is the classic Spinout puzzle that was patented in 1972 by William Keister. It was manufactured by Binary Arts which later became Thinkfun, which has a page dedicated to it.

Note: My version does not have the quick reset functionality, because that makes it (too) easy to cheat.

Instructions

There are 9 parts to print:

1x housing

1x carrier

1x dial1 (with flat bottom)

6x dial2-7 (with rounded bottoms)

The carrier has pegs which the dials will snap onto, and you need good layer adhesion to avoid damage when the dials are snapped in place. I used PLA, and had no problems, but you do need to apply quite a bit of force to snap them on. Trying to remove the dials will break the pegs, but there is no need to take them off again.

I used 0.2 mm layer height for everything except the housing, which I printed at 0.25 mm.

The housing will need supports in the slots along the sides, and this will be a pain to remove afterwards (took me 20 minutes with pliers, knife, and a flat headed screwdriver). In retrospect I could probably have placed the supports more carefully and avoided some of the work.
