3D Printer Frame (Fixed Bed)...

thingiverse

I've been searching for a 3D Printer Frame with a Fixed Bed design, but haven't found one that meets my needs. Since I've got materials to build my own printer, I thought I'd try creating one myself to keep everything from gathering dust. To start, I'm focusing on a lead screw design without belts, as it should provide the best results if I can minimize or eliminate backlash (although open to suggestions). **Motor Overkill** I've decided to use four motors to lift the gantry and two more for the Y axis. One motor may be sufficient for the X axis, but using two at opposite ends would allow for consistent tension on the hot-end/Y axis, resulting in better precision with a small added cost. However, this would require switching to belts on whichever axis I choose, which isn't ideal. My second design uses belts to drive the X and Y axes (note: FreeCAD adds extra objects when exporting STL files, so ignore those wheels). All parts are readily available except for the motor brackets on the X and Y axes. Does anyone know where I can get small aluminum brackets made? In the meantime, I'll print these, but for my final printer, I need machined parts for longevity and precision. I'll post more updates later.
