It is recommended to assemble the frame on a flat surface and to ensure that the extrusions are square to one another.

Fasten all ten M6x12 screws on the corner plates

Assembly from Step 2

90 Degree Corner

Install the 90 degree corner as shown

Fasten both M6x12 screws on the 90 degree corner

Assembly from Step 3

270mm 3060 Extrusion

T-Shape Joining Plate

Position the 270mm 3060 extrusion as shown. The distances shown should be as follows:

100mm

140mm

Install the T-shape joining plate as shown and secure all five M6x12 screws

Assembly from Step 4

2x 90 Degree Corner

Install the first 90 degree corner as shown

Fasten both M6x12 screws on the first 90 degree corner

Install the second 90 degree corner as shown

Fasten both M6x12 screws on the second 90 degree corner

Set the frame assembly aside until Step 8

2x M5 Nylon Locking Hex Nut

2x Rubber Foot

Fasten the two M5x25 screws through the rubber foot and into the M5 nylon locking nuts

Take care not to over tighten the M5x25 screws as you can damage the printed part.

3x M6x12 Cap Head Screw

3x 3030 Drop-in T-Nut - M6

Loosely thread the 3030 T-Nuts onto the M6x12 screws. Do not tighten them at this point.

Frame assembly from Step 5

Rear feet assembly from Step 7

Install the rear feet assembly onto the frame as shown

Make sure the printed part is flush with the end of the 3060 extrusion

Fasten all three M6x12 screws to secure the rear feet assembly to the frame

Take care not to over tighten the M6x12 screws as you can damage the printed part

Assembly from Step 8

2x M5x14 Cap Head Screw

2x Rubber Foot

2x 3030 Drop-in T-Nut - M5

Insert the M5x14 screws into the rubber feet and loosely thread the 3030 T-Nuts onto them.

Insert the assembled feet into the ends of the 3060 extrusion as shown. Fasten the M5x14 screws to secure them in place.

Place the frame assembly on a flat surface and make sure all four feet are level. The frame should sit firmly without any wobble.

2x 250mm MGN15 Linear Rail

14x 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.

The linear rail carriages are not interchangeable. Do not try to use a carriage on a different linear rail than the one it was supplied with.

Frame assembly from Step 9

MGN15 Linear Rail

Remove the plastic stops installed in the ends of the linear rail

Do not allow the linear rail carriage to leave the end of the rail.

Insert an M3x12 screw in each of the holes on the linear rail

Loosely thread a 3030 T-Nut onto each of the M3x12 screws

Insert the linear rail into the 3060 extrusion. Position the rail as shown with the following measurements:

70.00 mm

37.50 mm

Fasten the M3x12 screws, starting from the top

Double check the position of the linear rail, using the measurements above

Fasten the remaining M3x12 screws, starting at the top

Re-install the plastic stops at the ends of the linear rail

Check that the carriage runs smoothly along the length of the rail
