This is an easy to print jig for the Delta-Pi printer. It is parametric in the sense that the distance between the columns can be adjusted. Obviously, if you are having the base and top MDF boards CNC machined or laser-cut, you don't need this, but in my case, I am drilling these boards manually and so I designed this jig to help align the holes properly. Please read the instructions before printing. OpenSCAD source is included so the jig can easily be remixed and eventually used for different designs.You have to open the OpenSCAD source and edit it to generate the STL files to print the jig in two or three different parts. Apart from that, this is a relatively easy to print object. The thickness of the jig is also adjustable in the OpenSCAD source, I am using 1mm to reduce the time required for printing, but you may want to print thicker parts to get a more rigid jig.
