Hi! I'm a bit new to actually getting my hands dirty when it comes to both design and managing hardware.

I've been trying to print a few game sets of the board game Arimaa (we're showing the AlphaGo documentary at a film festival and I figured this would make an illustrative activity for AI discussions) and I've probably had a 50% success rate. I'm using a modded Davinci XYZ (filament feeds directly as opposed to using their cartridges). This is the set I've been using: https://www.thingiverse.com/thing:42032

I'm perfectly willing to edit or modify the files, but I'm not really sure what to do. My question is basically this: Is there anything obviously bad or unwise about the items in the link above and could it be fixed? We would love to both have smoother pieces and items that came out better. I tried printing this https://www.thingiverse.com/thing:44169 but it was even worse.
