Introduction

Please note: All measurements and component counts provided in this guide are based upon building a 300x300 V-Core 3.

If you are building a machine of a different size, please refer to the following list for the linear rail lengths and required number of fasteners:

200x200: 2x 250mm, 3x 300mm, 56x M3 Screw, 56x T-Nuts
300x300: 2x 350mm, 3x 400mm, 84x M3 Screw, 84x T-Nuts
400x400: 2x 450mm, 3x 500mm, 112x M3 Screw, 112x T-Nuts
500x500: 2x 550mm, 3x 600mm, 140x M3 Screw, 140x T-Nuts

Step 1 Prepare the linear rail parts

3x 400mm MGN12 Linear Rail
2x 350mm MGN12 Linear Rail
84x M3x12 Cap Head Screw
14x 3030 Drop-in T-Nut - M3
Please refer to the Rat Rig Linear Rail Guide (Steps 1 & 2) for full details on preparing the rails before installation
