I'm a mechanical engineer by trade, and I'm new to 3d Printers. I have extensive experience in 3d design using AutoCAD and Revit, but I'm learning more and more about 3d Printers. Only been in it a couple of months and am hooked. So far, I have the Powerspec 3D Pro 2 and a Flashforge Creator Pro. I'm building a BQ Hephestos w/diamond hotend and gonna take a stab at mixing my own colors. If you need help with designing anything, just send me a short note and I'll get back with you.
