All current copies of Swiss Cheese and Grape have been sold out (x25, it's a good start!). Thanks a lot for the encouraging comments and feedback ! It seems I was right and it is quite challenging ! So, don't be fooled by the cheesy look ! It's now time to produce a new batch. Still a few production issues to sort out due to current context, but I hope that it is now a matter of days. The 3D printers should be running soon, crossing my fingers. I am still in the process of estimating the right number of copies. So, if you want to be added to the pre-order list, just drop me an email (email@example.com). Happy puzzling ! Update : the new batch of Swiss Cheese and Grape has been released. Almost sold out already... There are 2 copies left! Check out the previous post for price and shipping. Say Cheese !
