Step 1: List of things you will need
Some graph paper
accurate way of cutting acrylic, saw
Some scrap acrylic or wood or anything similar. I used acrylic that was 2mm thick.
Step 2: Making the template
This gives an angle of about 60 degrees from the rear.
Once you have the template you can measure up what your going to make it out of.
Step 3: Cutting it out
My wife has done the cutting for me as I am not allowed to use her tools. After using her hand drill to inscribe my name on most of her stuff it became apparent to her that I cant be trusted with destructive things.
The pictures just show the process but really its fairly simple.
