Designed for accurate,cm-level measurement(especially small things).

Hardware:
Object loader(4 rotators on the front-bottom)
Height Regulator(between the loader and the platform,4 rotators)
Object platform(large cuboid block marked with black)
Clamp Holder(2 large panels,white,together with 12 rotators)
Ruler(Index value:5cm,on the clamp holder panel)
Ruler 2(On the square yellow block)

[How to use it]
In the garage:
Fix the object on the object platform,then load the game
In game:
Enable G1 to low down the object loader,G1 off
Use G2 to adjust the height(This thing can go really high but it will only disturb the holder)
Use G3 to place the ruler
Clamp the object with Clamp Holder,using G4
Read the ruler(The long red bars,long green bars must be parallel)
(If the object is large,please adjust the Clamp Holder first for bigger space)

After measurement:
Fix the Ruler 2 on the pink block(picture 3)[Bugs may can be found here,solve it by moving the ruler 2 lower,or moving the main Ruler],which has a index value of 9/10 block Loaded the game,use it as a vernier(remove the red block if needed).This will bring the equivalent index value to 5mm

If you need to measure something not symmetric,you can change the group of the rotators on the Clamp holder,but you need to use the ruler carefully
