Leather strap center finder/punch guide

This is a tool to help you find the centre line of a leather strap or belt, and then mark holes at an even spacing along that centre line.

Ideal for making clean and professional looking belts, straps for harnesses or other tack. The holes are set at 25mm (1") intervals, with the tab slots also at the same distance. If you so wished you could therefore mark at 12.5mm (1/2") intervals for a watch strap or other small item by using both sets of holes

The arms can pivot about the screws allowing free movement from 19mm to 50mm, allowing for 3/4"-2" straps to be worked on with ease. 

I use M3 screws, with heat press inserts to ensure durability.

Printing - I use ABS, 6 walls and 30% infill as I sell these and like them to be tough. However I think it would be just fine in PLA with 20% infill. Happy to get feedback and include settings if you try it in PLA.
