Here is my review on 75937 Triceratops Rampage. THE GOOD: The ride is surprisingly good. Looks great, good action features and build. The electric fences is great too. Love the tourist's facial expression. Getting a Lego Triceratops in a set under NZ$100. The set can be configure in different layout. THE NOT SO GOOD: The entrance felt like filler. Doesn't look finished as well. Overall, I think this set is a lot better than it looks. I originally thought it was just some simple build but the ride itself turns out to be an awesome surprise. There are also a lot of small details around the build. Apart from the entrance/gate build, everything else is great. I'm very happy with it and totally would recommend this if you are fan of theme park ride or Jurassic World fan.

I’ve been experimenting with 75937 “parabolic rings”, or “plate 2x2 with bar frame octagonal”, as bricklink describes it. I’m struggling to understand how it can connect to other elements, so I was curious - what connections are legitimate, and how do you use this part in your own MOCs? From what I can see, in official lego sets the parabolic ring is typically restricted to detailing like on the rathtars in 75180 Rather Escape, or the base for legs of Destroyer Droids: However, the ring can also be used as a structural element for brick built cylinders. You can connect 61252 plate 1x1 with clip horizontal and the studs will line up perfectly (left) and you can extend the assembly with bricks and remain “in system”: Changing the clip to 15712 tile 1x1 with vertical clip, it turns out the parabolic ring is 9 plates high, or 11 with two clips attached (left). Curiously, mecabricks says this is impossible, but it appears to work in real life. It turns out that in LDD and real life, the 1x1 tile part of 15712 has a slightly lower height than a standard 1x1 tile - why?? To keep this kind of attachment "in system"? It is certainly a useful feature, because if you add an extra two plates top and bottom, the entire assembly exactly matches a 6x6 plate (right). At least, it does in LDD (unable to test in real life and I'm not sure what CAD programs to trust any more). The two clip types are also equivalent. 15712 + two 1x1 plates matches the height of the 61252 (Left). The gap between them appears to be two and a half plates (?), but I’m not sure. The cylinder with the tile clips can be extended with bricks, but the plate across the top must be an odd length of studs. I assume this is like with technic triangles, where you count the gaps, not the studs, from mid-point to mid-point (right). So in this case it's a half plate from each of the parabolic rings, + 9 plates = 10 plates = 4 gaps: Now this where things get a bit crazy for me. If I build using the 15712 vertical clip, the whole assembly goes “out of system”. Zooming in between the 1x1 brick and the black tile, you can see a hairline gap - quarter, maybe eighth plate thick? What causes this gap? As a result, the separation between the two rings is slightly less than 6 plates, resulting in a collision at the halfway point: I’m not sure if this counts as being within lego tolerances. But how would you go about getting this kind of assembly back "in system". Is it even possible to close this gap? Does this even matter in real life? An answer is kind of important to me because I've been using it as a key component in a particle physics detector MOC that's taken me some months... I was just about to order parts when I discovered this "flaw", and I'm not sure how disastrous it is: Anyway, I'd love to hear your thoughts on these geometry issues. And do you have any other ways of building with parabolic ring? Are there any other interesting features of this piece that I've missed?
