Power Hacksaw by 3D Printer

I make a mini power hacksaw by 3D printer. Its base is only 35cm long. It can saw off about 50mmx50mm metal material; It takes 20 minutes to cut off a steel bar with 20mmx20mm;
At first, I use wood board to make a base. Now I use two steel bars instead. It's more easy to make by using wood board I think.
I just only upload the SCAD source code files, don't export the STL files; If your want the STL, please tell me, thanks.
