If anyone in the United Kingdom wants to buy a Blockmit jig (though I believe mine is better due to the ability to customize it!

) I just found out this 13 year old kit runs a 3D printing Bitcoin shop over there and has the jig in stock for 5£ which is a pretty solid price in my opinion.

I'm sure you could also send him a customized STL file of my jig and he'd print it for a similar price.
