Does anyone know the total weight of the BigBox (preferably the Dual) but any should do. I'm away from my printer with time on my hands and a sheet of Sorbothane in front of me (well, cooling in the Freezer) and I'm wondering what size to cut the material to. Having read the designers info from their website some donut / washer shapes seem the most efficient (if a bit difficult to cut - I've some brass I can roll and solder to the correct diameter then use it like a cookie cutter). Worst part is I made some shoes out of NinjaFlex that work fine and I don't think I have an issue but idle hands...
