At the time of writing my Kickstarter campaign has nearly 200 backers which means I need to make about 500 puzzles in June. With those kinds of orders it's worth making some jigs to help speed the process up. First thing for me was this large tape dispenser. Each puzzle gets a covering of vinyl transfer tape to protect it during transit but also to hold all the pieces in place. The roll is 200mm wide and 100m long so it needed something a bit more sturdy than the average tape dispenser. M8 bolts and bearings were salvaged from a very old CNC machine I built (before I bought a laser cutter). It's overkill but at least it's effective.
