Today, black Friday, Shapeways is giving 20% off all orders $75 and up. The coupon code is:tdzmu
The offer is valid until midnight tonight (EST). For the Europeans that's 6AM Saturday morning. You should check out the list of Shapeways puzzle stores
. This is a good chance to pick up my brand-new Open Pentultimate
To make everybody happy, I've uploaded two variants of my Switch Box puzzle to Shapeways so you can all take advantage of Shapeways' great offer. You can either purchase the original variant
or a new variant
which has all corners open (I think this one will be more fun, the original was a bit too difficult for my taste).
