WARNING - USE AT YOUR OWN RISK - YOU MAY VOID YOUR WARRANTY
It is recommended that you have a small shim between the laser unit and the arm bracket.
This part is 1mm tall and fits between the upright and arm of the LP2 stand. When you tighten the arm, you should not over tighten else you might put undue stress on the motor and burn it out. If too loose the part might get stuck and then also put stress on the motor.
The part might need to be thinner or thicker depending on the amount of play you have. 1mm seems to be a nice compromise but you should check.
