Hi, I am currently trying to source parts to build my own Wilson II. I want to learn more about building my own printer, and how to get good quality prints from a DIY 3D printer. However, I am having some trouble with prices (so far I have exceeded the price that I would pay for a kit). Can anyone recommend places to source parts from? I've tried Misumi for my aluminum extrusion and linear shafts. For things such as those I would prefer to stick to places where I can specify what length I want (can't really do much machining with the tools in my garage). Also, I am having trouble trying to find the MDF board, Heat bed PCB (200x300mm MK1), and Glass bed (need them to fit a print volume of 300x200x200mm). Additionally, I figured I could make the printer stronger if I didn't attach the filament spool on top but rather had a separate stand off to the side.
