Sadly the link doesn't work for me, but well, I am in Argentina so.
I honestly think we would be able to have a good go at a DIY one. As we haven't done one before, this might be a simpler and more achievable "group build" for a first try than say the furnace. I have quite a few heating elements salvaged from microwaves that would do a good job, and I wonder how compatible the laser plastic is for this.
Let's start asking around and see if we can drum up some interest!
