This is the remix. It can measure equal spaces of approximately 2cm (original 4cm) to 11cm. Simply print as many as you need (see formula below) to make it as long as you want.

To make a 5 measuring points tool, print the following:

4 x Equal_Space_Divider_-Long_sides.(F).stl 4 x Equal_Space_Divider-Long_sides(M).stl 2 x Equal_Space_Divider-Short_sides.(F).stl 2 x Equal_Space_Divider-Short_sides.(M).stl 5 x Equal_Space_Divider-Center.stl 6 x Equal_Space_Divider-1_layer_pin.(F).stl 10 x Equal_Space_Divider-3_layer_pin.(F).stl 10 x Equal_Space_Divider-_3_layer_pin.(M).stl

So, to make any length tool, use this formula.

To make a N measuring points tool, print the following:

[N-1] x Equal_Space_Divider_-Long_sides.(F).stl [N-1] x Equal_Space_Divider-Long_sides(M).stl 2 x Equal_Space_Divider-Short_sides.(F).stl 2 x Equal_Space_Divider-Short_sides.(M).stl [N] x Equal_Space_Divider-Center.stl [N + 1] x Equal_Space_Divider-1_layer_pin.(F).stl [N*2] x Equal_Space_Divider-3_layer_pin.(F).stl [N*2] x Equal_Space_Divider-_3_layer_pin.(M).stl

I've printed this with PLA and added a brim to secure the parts to the print bed. The pins above are not 100% secure, so maybe drop a little glue into it to make it stick.

I hope someone finds this useful.
