@the bandit, haha oddly enough yes that thought did whiz through old grey matter, was thinking of making a play house for the nephews and nieces which they could all help build, I think I calculated that It would take about 2 days to print the 1 brick, by the time I had enough bricks the kids would have grown and I’d have to build more bricks haha, then they would be too old. It would be much quicker to injection mould the bricks.
