Ikea Lack Enclosure - 4.5mm Foam Board Version

Here's my remix of the original Prusa Ikea Lack Enclosure for my Ender 3 (https://www.thingiverse.com/thing:2864118) that uses foam board instead of acrylic sheets.

The decision to use foam board was based on:

1. It has better insulation properties than the acrylic due to the foam density (R = average 3.6 per inch = 0.673 for 4.65mm vs acrylic R = 0.7 per inch = roughly 0.082 for 3mm) thus keeping in more of the heat for ABS printing (there are still gaps everywhere to let off most of the excessive heat)
2. It was a LOT cheaper! I paid a grand total of CAD $12 for all of the pieces and still have plenty to spare!

The foam board has an average width of 4.75mm so I changed the original design to be 4.5mm wide, providing some "grip" for the foam board.

I have not included the PSU bracket and spool holder as these aren't specific to the enclosure at all.

Instead of modifying the original files, I decided to redraw all of it using Sketchup as a learning experience. I feel this went fairly well.
