I've been planning to build myself 'n wine shelf. This required equal spacing between the bottles. Measuring the full length and divide by the number of bottles doesn't give you the feeling how far apart they will end up being. I search the internet and nowhere could I find a tool that would make this easy.

Along comes this tool. Easy to print, easy to use, and fairly good results. It can measure equal spaces of approximately 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:

5 x Equal_Space_Divider_-_Center.stl
8 x Equal_Space_Divider_-_Long_sides.stl
4 x Equal_Space_Divider_-_Short_sides.stl
6 x Equal_Space_Divider_-_2_layer_pin.stl
10 x Equal_Space_Divider_-_3_layer_pin.stl

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

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

[N] x Equal_Space_Divider_-_Center.stl
[N*2-2] x Equal_Space_Divider_-_Long_sides.stl
[4] x Equal_Space_Divider_-_Short_sides.stl
[N+1] x Equal_Space_Divider_-_2_layer_pin.stl
[N*2] x Equal_Space_Divider_-_3_layer_pin.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.
