Thats right, bubble wrap! There was a small problem with visibility, so I cut a small hole in the front that I kept taped shut to avoid heat escaping.

I was concerned that the filament could get caught on the top cover, so I taped the top bubble wrap up out of the way.

It worked so well and is so cheap, I think I may 'refine' the design. More photos to follow in the future.

Whilst pulling an all nighter printing parts for a prototype that had to be handed to the client the next day, one print just kept causing me problems. After a quick bit of searching, I realised a cover would help. But I was short of cash, materials, and even shorter on time, so I had to think quickly and use what I had a round me.

The attached image is the result, and I must say, it worked beautifully, and kept the heat in extremely well....
