Well, we just picked up a CR10S 500, and to test that 500mm X/Y/Z, we're going to start doing a massive monthly (Monthly Massive ™?) design. This one is about 22" tall (14" for the body of the tower and another 8" for the top. The interior is fully textured, with stairs and platforms winding to the top.
Before anyone asks, no, we won't be splitting models from this series into pieces that can print on more common printers, -BUT- we are leaving it open to remixes, so one of you could be that hero! We printed at a .2 layer height and it used about 1 1/4 spools of black PLA (and took about 3 days). Model is shown with a bunch of our ScatterBlocks.
Quick plugs: If you're interested in supporting us on Patreon, you can get access to our full range of products, exclusive models, and sell printed versions of our designs (depending on pledge levels). Also, we're currently Kickstarting our Townsfolke support-free printable villager series, so drop on by if that interests you.
We hit a filament snag right near the top, but Jeremy8077 pulled a print-hack and salvaged it. Such is the danger with three-day prints.
We painted ours with a big ol' tank brush using Reaper acrylics directly onto the black PLA filament (no priming).
