Bill of Materials

I shall update this list gradually. All links are given as reference and you may find cheaper sources.

For the main rails choose the length you wish (I have ordered 1500mm)

1. v-slot-2040 

 For the X carriage:

1. 625-POM-Plastic-bearings-625-PA-Glass-Balls-size-5x16x5mm
2. OpenbuildV-slot-Plastic-Wheel please order the wheel without the steel bearings.
   Also do not forget to install a washer between the two bearings of each wheel to prevent locking the bearings when you tighten the bolts.
3. 30 mm long aluminum bolts
4. 36-teeth-Bore-5mm-GT2-Timing-Pulley-fit-width-6mm-of-2GT
