My parents were in the habit of putting on elaborate Halloween parties for a few years. One year, the theme was “Alchemy.” I helped them make some extra-spooky invitations by laser-etching fake apples with the party information and making custom boxes for delivery.
This was an interesting problem to solve both because of the size/shape of the apple and also because I needed to make 30 all the same. The rotary attachment for the laser cutter was meant mostly for glassware which made it difficult to fixture non-hollow objects. I improvised a “jig” of sorts to accommodate for this issue by hot-gluing a paper towel roll to the top and bottom of the apple which helped center the content and allow for proper rotation. The hot glue was easily removed and left no residue on the apple so I could re-use the “jig” many times.
