Couch Spud is a simple and effective customisable tray.
Key features include:

• fully customisable
• drink holder/s to stop cups slipping
• words/letters can be engraved on the base.
  The tray is particularly useful for couch potatoes when you need a tray for your drink, food and remote but only have an arm rest or some limited space available.

Set your parameters in customizer and generate. It is very easy to print with no special instructions. High speed settings can typically be used without issue.
