I think the other consideration to part size needs to be addressed. I have had a Moto 360 watch. The band on it isn't longer than 5" for one half of it. Try to keep your design to a single piece of the band to 5" or less (X axis)
My band actually measures 3 1/2" on the buckle side including the buckle and 5" on the 2nd piece of the band with the holes side. If we keep a max part 5" or less, it will help greatly with printing them. Watch how thick you make the band as well. If you get too thick, the ABS plastic won't bend (assuming you produce a solid band) If you come up with a different design that "hinges" in some way, then thickness isn't as big of a issue.
I do feel this competition is very valuable in teaching Design for Additive Manufacturing. As a manufacturing supplier, we see this area growing more and more each year. Manufacturer's are constantly asking us if we know of people who are versed in Additive production / manufacturing as they are looking for that skill set in future employees. It is a trend that has been slower to catch on in Nebraska, but is very much the norm throughout the country. Iowa manufacturers have an enormous amount of 3D printing being utilized and I think it would surprise most people the amount that is being done here in Nebraska. Take a look at what the major Universities are doing along with our Community college system. They all teach and utilize 3D printers. Students need this exposure. I' even have Math & Science teachers (in high schools in Nebraska) learning and teaching with 3D printing. Let's not give up on this competition and the way we teach students CAD modeling as this industry is here to stay and very much the way of the future. We don't see any 2D drawing happening anymore....just saying.........
If any of you have a questions feel free to contact me directly.

Advisors,
I want to apologize for taking so long to get you an answer on the Additive Manufacturing contest. I was really hoping SME was going to give us a state only contest for this year, as they are really keeping secret about what will be happening at Nationals. This contest is not one I really feel comfortable with, along with a whole bunch of manufacturing people in the Omaha area. I think as of today, we have a contest coordinator, but I do not have a name!!!
I am stealing an idea for this contest from another state and the contest is below. Your completed design will need to be sent to (hopefully Tim Watters) and we are hopeful he be around to produce these and also have a 3-D printer at SLC to produce another design you will have to do during the conference.
I am attaching the Technical Standards from last year and we will follow these except for the actual product your students will be designing. Below is what they will need to design. Time is now a factor, as I am sure you are holding back nasty words aimed directly at me!!!! The teams designs will need to be sent to Tim Watters by 4:00pm on Monday, April 18, so as to give him time to print them out. I really hope for more information to come your way early next week about this contest and what will be expected of your teams at state – also the engineering book.
The design problem will be a Watch Band for the Moto 360 (1st Gen) smart watch. With the build envelope no greater than 6.5"(X) by 1"(Y) by 0.5"(Z), when the watch band is lying flat. The watch band design is determined by the contestants. Watch band must be able to attach to the Moto 360 (1st Gen) smart watch. I think we are looking for something innovative, attractive yet strong
