Now that I've had the 50mm 3D print of the 50mm floor part for a few days in my hand, and seeing how miniatures look on them, I'm now wondering if 40mm really might be a better size for the floor tile after all? 40mm will still take 25-40mm bases, and look less bare with the smaller based models than 50mm. It's true 2 x 25mm based models can stand side by side on the 50mm tile, but many miniature manufactures now use 32mm bases and they do not fit neatly side by side onto a 50mm base so that justification is gone. Considering the future trend of base sizes are probably going to increase (they started out at 20mm!), the part has to look good with 40mm and 32mm bases.
In regards to 'Space Hulk' I think the 40mm tile with sloped walls could accommodate the awkward genestealers with their wide arms (around 50mm across) despite their small 25mm base. I think I can thin out the wall top to around 20mm to get 40mm (floor) + 10mm (slope indent) + 10mm (slope indent) to get a total of 60mm from inside wall top to opposite inside wall top. Maybe even thin the top wall down a bit more, to around 15mm to improve that distance to around 65mm.
While rescaling I made a couple of refinements to the part: the grill is a little more chunky on the 40mm, to test it out and see what it feels like once printed. Also tweaked the connectors to see if I can tighten them up a bit.
Hearing feedback is very important to me in developing my ideas. Much of my designs are inspired, and crafted, by chatting to fans on forums before snowballing into a full concepts posted on this website. I would like to thank all those who have contributed critiques and participated in discussions over the years. If you would like join in, you are most welcome!
