I found the YouTube video for this a couple months ago and made it a week or two after watching it. I didn't want to use the whiteboard and have to replace it often due to the humidity, so I used a sheet of corrugated plastic (3'x8') that was also at Home Depot for about the same price. $13 and some change I think. I used screws that are rounded at the head and the 28 qt tubs to fit up to 18 snakes. The tubs barely touch the screw heads, but it kind of locks the tubs in place. To wire my heat tape (also separately) I used a 12 gage extension cord. Trimmed the insulation off, (a little over a half inch) folded it, and stuck it in the connectors until I got to the last one. It was nice to read and see what others have done as well.
