Don’t bin that, repurpose it!
Here’s a handy tip for anyone with access to a 3D printer - even if it’s just one at a library or maker space.
Often 3D items need to be printed on something that’s called a ‘raft’ (a small, thin, flat layer) that helps the item stick to the printer bed during printing. These are normally discarded after the item has finished printing and been removed from the machine. START SAVING THEM!
I don’t use rafts anymore since all of my machines now either have a heated bed or a build surface, but luckily (or rather, because I’m a secret hoarder!) I tossed mine into my failed prints box rather than the rubbish bin. I now have a load of (a) ready-to-use scenery bases, and (b) oodles of mesh/grid work for kit-bashing.
So even if you don’t use a 3D printer yourself, go ask anyone you know who has one (or whoever runs the printers at the library/maker space) if they can save them for you.
