Ball Caster

In this section, you will be adding the ball caster to the bottom side of your bottom chassis piece.

Locate the following:

  • 4x M3*6 Screws
  • 2x L25 Metal Standoffs
  • 1x Ball Caster

There are different types of screws in this kit. Make sure you use the M3*6 screws for this section.

Pick the right screw

Place a M3*6 screw through one of the ball caster's holes. The screw's head should be on the same side as the ball caster's metal ball. Then screw in one of the L25 standoffs to the ball caster. Please note: the L25 metal standoffs will be longer then the L10 metal standoffs.

Screw in ball caster

Using a M3*6 screw, screw on the second L25 standoff on the other side of the ball caster.

Second stand off on

Locate the two positions on the chassis piece where you will be screwing down the ball caster.
