3d printing pen

[Helen89]

I once ordered MYNT3D 3D pen for my son for his birthday. We followed the instructions exactly and could never get the motor that pulls the line through to work. Followed website guidance which led me to the advice to return the defective device. Well, OK, maybe we just got a dude. Ordered a replacement and I'll be, the motor on that one would only run in reverse. Opened the pen up, examined the engineering and determined that this pen was designed by Dopey of the 7 Dwarfs. So, I am not sure it is a good idea. I'd rather play the new upcoming slots than get into this mess at all.
