Here’s the model in the picture for those interested:

Tak Game by craeen
A variation (in looks) of the game "Tak: A Beautiful Game" https://www.amazon.com/Cheapass-Games-239CAG-Tak-Beautiful/dp/B01LFA7QFK/ref=sr_1_1?ie=UTF8&qid=1517029133&sr=8-1&keywords=tak+game You can play the 4x4 or 5x5 or 6x6 game with this board.
I used the wood grain from https://www.thingiverse.com/thing:1640999 then designed the board and stones using Photoshop and Tinkercad. For the capstones I chose 4 files from the following three Thingiverse items and forced them all to be 20mm x 20mm at the base and 32 to 35mm tall.https://www.thingiverse.com/thing:1079138https://www.thingiverse.com/thing:935856https://www.thingiverse.com/thing:1254404
Everything was printed in Hatchbox wood PLA and stained. (The red "rocks" were painted with 3 different paints). The board pictured was printed in 4 parts. (I'm also including files to print it in 2 parts or all at once if you have a large printer). If the pieces warp when you take them off a hot bed, just place them back down on the hot bed and hold them down until they flatten back out. The woodgrain and border give the stain "capillary action" so it's actually pretty easy to stain it 2 tones (use a cheap paintbrush).
We like it in 4 pieces for storage, but on a slick table the pieces tend to slide, so we put a piece of our painters tape on the middle underside.

I came across a really clever idea today for minimizing warping on a large flat
surface. The modeller made the first two layers into a series of bridges, which
seems to let the plastic shrink and stretch a bit, also preventing some possible
blobbing.
At least I assume that’s what’s going on here. I’ve never seen it before, but it
printed great without curling or warping.
I’ve also picked up some looser ideas. Things like: - Adding a 0.02 tolerance to
interlocking part will help parts fit together. Adding small chamfers to edges
will also help - 3 shells helps give a nice, smooth surface - Orienting parts on
the bed so that layers are perpendicular to stress can prevents layers from
delaminating in functional parts - Orienting parts such that fine details are
vertical will help things look prettier - Add slight chamfers on the underside
of overhangs can help minimize or even eliminate the need for supports - Create
inset holes with this method

eliminate the need for supports. This also works with other shapes
