3D printer made from Meccano and hot-glue

This prototype 3D printer was built out of Meccano (a Commonwealth analogue of Erector Sets, but infinitely superior in every respect) and a hot-glue gun. A sample of its feats: "[it] automatically lowers itself up to 60mm, currently at 0.75mm per revolution though this can be changed. This is intended for use in experiments in continuously
extruding recycled HDPE…

"Recent fabrications include a 18mm high 19mm diameter cylinder with 0.85mm walls, and a 13mm high 43mm diameter cylinder with 1.75mm walls. Each layer is 0.25mm thick. It's fascinating to watch in the same way as a potter is, at work on their wheel."
