Even when doing other things around the house, I still find the odd jobs for the 3d printers, I was tasked with replacing the tap washers on the sink and bath and then decided to make new coloured rings for the top of the taps while I was at it..
It really is amazing how many things I find that I can fix/make that are helpful around the house. Many of which are unique and I'd have a difficult (or impossible) task of finding online pre-made.
