| M6 × 30 mm | 12 | |
| M6 × 35 mm | 4 | |
| M5 × 50 mm | 8 | |
| M5 × 20 ~ 25 mm | 20 | |
| M5 × 40 mm | 12 | |

| M4 × 16 mm | 100 | |
| M4 × 10 mm | 8 | |
| M3 × 15 mm | 16 | |
| M4 nuts for VSlot | 100 | |
| Wood screw 4 mm | 20 |
For each line of screws, also think about the nuts and a few washers.
M6 × 35 mm is VERY important for screwing the spindle mount onto the Z carriage, if the screws exceed this, it blocks the carriage.
M6 × 40 mm very important for the T8 nut mount on the X & Y carriages.
Recommended printing parameters
Suggested settings for printing the parts (although not mandatory):
- Layer height: 0.2 mm (0.3 mm possible)
- Infill: 50% (cubic)
- Walls: 5 perimeter lines
Where to buy the components
I find most of the parts on Amazon (the links in the materials list) except for:
- The long T8 trapezoidal screws: I buy them on AliExpress.
- The aluminum profiles: I buy them from Systeal or Dold-mechatronik.
- For the router/spindle, I use the Makita RT0700C, but there is also the Katsu 101750, less efficient and less precise but half the price of the Makita.
