Review on 400mm (15.75 Inches) TR8X2 Thread Printing Machine by Sheppard Priest

Excellent thread quality on these lead screws. If you are wondering how much you will get: FYI if you have 1 piece you will get 2 lead screws. I'm returning add-ons that I accidentally bought. I upgraded the 2 leadscrews of the Anycubic i3 Mega S printer. They need to be shortened from 350mm to 330mm. 350mm would be too long for the i3 Mega S. You'll need a power blade/grinder to cut them down (they actually cut steel quite easily), then you'll need to file or grind/grind the ends of the threads so they aren't sharp. You can install them without cutting off the connectors on the cut end. The couplings sit perfectly on the thread, but what I didn't like was that they weren't screwed. I have found that couplings with M3 threaded holes are rare so you will need to use nuts to secure them. I would buy them again in a heartbeat if I had to.
