About this Product
This puzzle is very much like a mass-produced Square-1, but with the addition of internal blocking to make solving more difficult.
This model comes with all of the plastic parts you will need to complete this puzzle. It comes with extra parts, so you can experiment with different numbers of restricted and unrestricted parts, and so you can toy with the internal blocking. This puzzle requires a single #4-40 or M3 screw to be put together, but the length of the screw is not too important; anything above a few mm should work fine. You will also need stickers, and since this puzzle is based largely on the dimensions of the mass-produced Square-1, regular Square-1 stickers should fit just fine. That being said, I can cut and ship you stickers for a small fee.
I strongly recommend ordering this puzzle as a DIY kit, rather than having me assemble it for you. I say this because this puzzle is designed to be customizable, giving you the ability to rearrange parts to change the blocking structure of the puzzle as you like. Moreover, this puzzle is one of the easiest of my puzzles to put together, and assembly is largely the same as assembly of a mass-produced Square-1. While I can offer assembled versions, I think you’ll be better off learning for yourself how the parts go together.
