Hello and welcome to my family ran shop , feel free to browse our amazing creations , from my 3D printed model replicas and movie props to my wife's dolls house food and miniatures 

I run five of the ctc dual replicators to make my models , I buy these parts for my machines , so , I'm not just a reseller , I know these machines , I've practically rebuilt one of mine and I've had major issues with another , I've had every problem you can think of from changing electronics including motherboard , layer shifting problems , limit switch troubles , rewiring , machine juddering , heavy vibrations, prints not sticking , the infamous clicking noise ( stepping of the motors ) and most common blocked nozzles , I have also successfully installed sailfish five times onto ctc dual printers , if you are pulling your hair out like I have many times feel free to message me , I might be able to give some advise thanks
