for a 1 meter tall rostock what would the recomended rod thickness? 10mm rods or 12 mm rods?

15 plastic kits in powder sintering (SLS)like I can sell:

I know its a late reply, but FWIW I always use stainless fasteners on something like this. The price difference is almost nothing and it means your beautiful printer won't end up with rusty fasteners.

Looking forward to the continued development of the printer!

I would love to see the legs be able to go inverted for a ridiculously tall print area too ;)
