There is a .stl file, the original total diameter is 1m, height to the upper small parabolic mirror is 560mm include depth.
Calculated power is nearly 1200 watt. Under real condition maybe 800 watt or more.
For less area more power than with a fresnel mirror
I'll use a silver rescue blanket (mylar foil) as reflector material, to glue and vacuumize it (vacuum cleaner)... or maybe with cnc.. hope it works
Maybe you should to resize it for your printer, too ;)
