I know, I know. In the photos of this project there are scratches on the casing, there appears to be a massive hole that looks as though it was cut with a chainsaw, there is glue all over the place, the 3D printed parts look as though they were made on M.C. Escher's printer. 

All I can ask is please forgive my poor workmanship. It was the best I could do given my circumstances at the time.

I will endeavour to highlight alternative methods, materials and/or tools as we cover the worst bits, which should help you to achieve a more refined article.

Now, onward...
