For the more perceptive ones, I've 'recycled' ('upcycled' might be a better word in this case) the tail design I've used on the Skyrays and Hounds. The main reason was that the previous version of the tentacles were just unworkable since my computer couldn't handle it.
However, it would have been a bit lazy if I simply used a magnified version of the tail and didn't modify it in some way. As you can see, I've been adding some rivets on the now-tentacles as well; this kinda detailing would be impossible on the tails since they're 50% smaller).
Also the spikes themselves at the end of the tentacle have been modified: longer and sharper, but also with some detailing. I'm still a bit curious is these would be printable since the printer might see it as too thin. I'll try to throw it in Shapeways as soon as possible just to see what their checking-system says (don't have the budget yet to do test-prints).
I just noticed a slight mistake on my part. The human model is a bit bigger than it's supposed to be - 33mm instead of 30mm. The reason why I picked 30mm instead of 28mm is twofold: (a) 28mm scale models tend to be 28mm from the bottom of a model's feet to its eyes; (b) there has been an upscale creep throughout the years, meaning "28mm scaled" models are often around 30mm or even 32mm tall. Just put your old Imperial Guard or Space Marine models next to the contemporary ones to see what I mean.
The 'Squidwheel' (still don't have a better name for it yet) is about 60mm tall and stands on a 40mm round base. One challenge point is that the buzz wheel isn't the most stable of objects to be put on a base like that. So the plan is to design a base-surface for this one, which will probably be the ruined remains of a surface dweller's home or something.
However, this is where I need your help. Since I don't have my old bits box anymore, what are the exact dimensions of a round base? So ok, 40mm diameter on the bottom. But the top diameter is slightly smaller, how much smaller? And how tall is a standard base? Up until now I've been using 5mm for that, but I've got a feeling it's a bit less. Help?
