We could do what we do for Mini2 (quick circle & octopus), but it would be great if we could come up with something that would be good for dimensional accuracy and also send to the customer that would take less time than the traditional octopus which runs about 40 minutes on average.

what do you think of these?

I think it's nice, but I will leave that to @logan or @DRobertson if it's going into the box to the customer. Will this be used just to calibrate the printer and then thrown away or will this go out to the customer?

all the above

If this is going out to customers, marketing will need to give at least the thumbs up. Are there enough measurable points on this to conclude calibration and that the printer is operating as it should? If it's functional enough to complete calibration, then I'm ready to sign off on it.

I like it, mainly because it is quick.
Would we still want to do a quickcircle tower for dimensional accuracy? The two prints together would only be about 20-25 minutes print time, which would be our shortest calibration print time yet AFAIK.

We can actually use the gear for dimensional accuracy. if you measure apposing spokes and the ID and OD of the center circle, you should be able to get enough data to tell for the printer is printing correctly

these have better whole value dimensions to measure.

If you think we still need the circle tower in addition, then I am for it

What if we made the center circle of the gear a bit taller so we can get the calipers on it straight? That would help.
What is the center circle dimension, and what would the upper and lower limits be?

The ID is 16mm, I'm guessing we still want to achieve ±0.2mm. We can definitely increase the cylinder height. Do you have a recommendation on ideal height

An even 10mm? Shouldn't add much print time since it is open and not filled

Sweet!
@DRobertson can we get an approval on this as the workhorse print that will be going with the printer?
Also, what material? PLA or nGen?
I'd like to get that approval before getting this into the OHAI

I would reccomend PLA just to keep things easier on the Supply chain and manufacturing but that's my two sense.

I agree completely.

I think this file looks great. PLA sounds good as well. Let's do it.
