Folger Tech FT-5 170mm Alignment Tool

This is a tool for building the Folger Tech FT-5. It calls out to space the two upper levels 170mm apart. Had no way of doing it. My dial calipers only went to 6" or a little over 152 mm so I just made my own tool to do the job. Nice to have a 2nd 3D printer handy!! I used Tinkercad. This is my first time using it. It only took about 20 minutes to design.

Note: I had them measured and off of my Rostock they came out 173.23 mm. Should be close enough to work. I will be fixing the length proble
