I'm interested in creating some basic shapes out of acrylic but don't
want to cut acrylic sheets or order custom cuts from manufacturers.

My shape is basically 0.75" thick x 2.50" long x 3.00" wide.

I need to create alot of these quickly and inexpensively.

Are there at home acrylic polymer kits I could use or could I create my
own mold and buy off the shelf acrylic to create these?

I am a newcomer to plastics and don't know where I could buy acrylic
liquid and what I should buy, etc.

Thanks for any help.

Mike
