Drop the belts down to MK2 or MK3 and then it would be very useful. Switch up to multiple input of iron and overclocking to run better results.

This is such a weird blueprint. It's using Mk6 belts so it's useless to someone in early game, but it's such a random assortment of stuff that I can't imagine why you'd want it in late game...

And for what exactly is useful to produce Motor 3 Rotor 3 Stator 3 Portable Miner 0,5 Modular Frame 6 Reinforced Iron Plate 8 Cable 30 Iron Plate 15 Iron Rod 15 Wire 15 Screw 10 Steel Pipe 15 in MK.6 phase? Make it with MK3, or MK4.
