I’ve at all times had a factor for sprues, the plastic frames used within the injection molding course of and to carry mannequin components in place. Anybody who does any scale modeling or tabletop sport modeling doubtless has tons of these items mendacity round (in case you do not throw all of it away). I am at all times on the lookout for new concepts of the best way to re-use sprues.
Jon at Miniature Hobbyist is critically sprue-obsessed. He not solely has dozens of concepts for the best way to re-purpose sprues, he even breaks them down in acetone and creates what he calls “Oooey-Gooey Spruey.” He makes use of this liquefied plastic materials as gap-filler, to extrude tubing and hosing, and as a casting medium.
On this video, Jon creates an Ork Tie Fighter fully out of sprue.
This is a piece I did on Adafruit about his 4-part video collection with almost 40 totally different sprue-use concepts.
