Makertober Day 18: Making a working printer

I think you should all know that the little plastic rocket above was the product of a lot of effort today. In the end I discovered that last time I mended the printer I’d left a tiny gap between two parts of the path into the print head. If the plastic in this gap melted it then formed a plug which blocked everything up. All I had to do was take the printer to pieces, put it back together wrongly a couple of times and then finally get it right.

So I know have a 3D printer that works. As far as I know.
