This scale is used when playing Faster Than Light (FTL) to measure the number of jumps you can make before the fleet overtakes a specific destination to help you properly route plan your path through the sector. 

The Scale is made at 10mm main spacing (normal jump). You will need to measure your specific spacing on screen and scale the object appropriately. 

As an Example- on my iPad the normal jump is 13mm so I scaled it 130% in X and Y (keep Z 100). While on my PC in the standard window is 20mm, so scaling is 200% X and Y.  Yours will be different. 

To use it- keep it horizontal and put one point on the current fleet line location then simply count the large points. Smaller points are Nebula jumps and you can use either as needed. 

I added a “Mini” version if you don't need the larger one or you are using a very large monitor so printing at 200% made it too big for your printer. 

NOTE: I have included a STEP file so that you can easily edit this or remix it. I encourage everyone to always include STEP or another CAD format to make sharing, editing, and remixing easier. We all know what a hassle editing an STL is so be a good community member and share an editable file format.
