The idea for this came from Thing 11977, although the design is all new.

Basically, it's an apparently impossible dovetail joint that opens by rotating. My interesting little observation was that it needs almost no thickness, and no core, in order to lock and rotate well. It's a tiny empty box. As a result, this prints in a few minutes on our MakerGear M2 -- it prints better and nicer scaled-up 2X.

There are two versions here as STL files: one with the new University of Kentucky logo on one side and our department name (ECE) on the other, and a second plain version. The logo one was made in quantity and handed-out to EDay Open House visitors to our lab; interestingly, we had no problems fitting pieces together that were made on either of two MakerGear M2 and one Wanhao I3.

Printed in 0.25mm PLA scaled-up 2X. Prints as well on the Wanhao I3, but takes a lot longer than on our MakerGear M2.

Don't encourage that "new logo", it's horrible. :)

Unfortunately, I personally agree with your sentiment. The new logo looks a lot like the logos of certain other universities and also has very serious scaling problems -- it actually has a very thin edge that makes the smallest fully correct 3D-printed rendering of it nearly 2" across, which is way too large. In general, it's a terrible logo for anything small, including business cards. Ironically, the sports logo you are using is very similar and comparably unfortunate.

In any case, the UK administration didn't ask my opinion on this. I just try to be as compliant with logo usage guidelines as I can be, and for our open house it certainly makes sense for us to be doing things that strengthen the UK branding....

For what it's worth, I'm personally not thrilled with the university slogan either. When I came here as a chaired professor 15 years ago, I really liked the multiple-meaning "A tradition of value." slogan -- which they promptly changed to "America's next great university." and I hated that because it implied we were not already great (I wouldn't be here if I believed that). Anyway, now it is the very sports-oriented and generic "see blue."

Don't let the so-so branding fool you. UK really is a top-quality university: Carnegie classification R1 ("Highest Research Activity"), committed to providing excellent education, and with a long tradition of being scary-good at basketball. ;-)

Don't need to sell this graduate on the school.....the plain logo I use lends itself to 3D design and printing, IMO, I've used it on a number of my designs. Have a good day, Prof!
