The Casebag - make the Lian Li Dan A3 portable

Since I take my computer with me quite often, I wanted to create something that 

1. does not take up as much space as a large bag, but 
2. makes it a lot easier to carry the Lian Li A3 case.

The result is made up of no more than 

• two printable base plates, 
• two pack straps (each 120cm long and 2.5cm wide from Amazon), as well as 
• one large carabiner (also from Amazon).

Simply slide the base plates from the front and back under the case and start carrying. I recommend printing this with a high fill setting.
