I love Catan and I love designing miniatures, but I hate cleaning printed parts.
I have spent months designing and tweaking each of these pieces with focus on: - Minimal cleaning (no supports, no retraction, no melting thins) - Ease of printing (no brim, no raft, nothing too small or unstable) - Ruggedness - Adorableness - Ease of use in-game (e.g. roads now much easier to grab and place)
As you know, for the basic game you will need (for each player color): - 15 Roads - 5 Towns - 4 Cities
Note: there's a version of City01 with the hole for a Metropolis flag (in case you ever consider the Cities and Knights expansion, which you should be.)
Note too: I've added the ship from Seafarers to this basic set.
For printing: I recommend 0.8mm walls, 0.8 top/btm, and no infill. For the ships, you might have to dial down your 'minimal time spent on layer' setting...
