Major improvements - to keep strong structure i decided to use Aluminium L type profile for base and for bed (sizes depends from .your local stores, my 15x15x1.5 for base and 10x10x1.2 for bed support)

Hot end - i have a few ideas, seems like it would be PTFE body with 6mm stainless steel barrel (or PTFE barrel), e3d v5 heater box and e3d nozzle.
All other parts are designed and (mostly) printed.
