Step-by-Step Instructions
Individual parts broken down into short 1-3min. videos. Some with time-lapse to keep it short – but still show the techniques. (As mentioned – still work in progress, so please send any suggestions to jude_pullen@yahoo.com ). The main objective here is to allow you to clearly follow the process – but – become comfortable enough with these techniques to make it your own. Good luck & happy modelling!
Screenshots
A quick overview of the main parts of the tutorial.

Sketches
Work through a few ideas you might have in rough first. It often save time/mistakes.

Rough-Mock-Ups
Don’t worry about being too accurate – play around with different styles/materials.

I’m Sticking With You…
Yup, this part takes a while, but the result is pretty unusual, I think.

Simple Window
You can always make a simple viewing window, rather than Light Pipes.

Professional Light Pipes
For the modelling connoisseur. Some useful dimensions here too.

Score & Snap
Easier than you think – and saves a lot of time once you get the hang of it.

Super Glue (Tip)
Super Glue does not stick to Insulation Tape – really handy to know for modelling.

Light Pipe Test
Gives a surprisingly large area of light – even from the tiny LEDs on the Board.

Check Before Gluing
Works of wisdom (from those who have messed up many a model in the past!)

General Assembly
Build the box around the Raspberry Pi, taking care not to burn your find your fingers!

Tricky
Glue the Light Pipes to the Board surface. Adjust while glue dries. Take your time.
