Decided to redesign my printer, so I made this one instead. It features a significantly improved linear bearing placement and more secure M5 nut placement too. The elongated M5 nut section is designed to prevent nuts from sliding out occasionally. Also, you can see the rods' middle section clearly because it serves an important purpose: if the holes ever widen and the rods loosen, you can wrap a clamping piece around this section and clamp them down tight. The design also incorporates some extra style. It looks cool that way. To print this with one easily removable support in the linear bearing section, use Slic3r settings like these: 0.26mm first layer height and then .16mm afterwards. For Pattern Spacing, set it to 6mm; for Interface Layers, 0 should do just fine. I used PLA filament, and happily, my holes turned out perfectly.
