-24" x 12" sheet of 1/4" thick acrylic (1/8" would probably work)
-~18" of 1/2" OD acrylic rod
-Acrylic solvent cement
The materials can all be found at TAP plastics or a similar plastic supplier, and a laser cutter can be found at TechShop. I designed the file using Autodesk's AutoCAD, also available for use at TechShop along with lots of other software.
Step 1: Step 1: Cut the pieces using the laser cutter
Step 2: Step 2: Cut acrylic rod and glue together
Note: the acrylic solvent-type cement works best in small quantities, so don't put too much on, just follow the directions given with your particular cement.
