"Universal" jigsaw piece, connects with itself on every side

thingiverse

Done with this remix check the new interlocking tile, no longer universal. This is my first attempt at creating a blank jigsaw piece capable of connecting to copies of itself on every side. The intended use is for Scrabble - interlocking parts prevent easy scrambling. Hence, the design features connections at all sides. Naturally, it shouldn't be used alone; that would be boring. I searched for something similar but couldn't find it. Either it doesn't exist or my search skills are lacking. One problem just arose - apparently, four pieces can't connect to form a square. I knew there was something I missed. That's why this project is tagged Work in Progress. Print Settings: Rafts: Doesn't Matter Supports: No Resolution: Anything goes; it's not detailed. Notes: I've achieved success printing two tiles simultaneously, but it's not perfect. It saves a lot of time, though. Be cautious and inspect the tiles after each print. They're small, so something can easily get stuck and ruin the interlock. Layer height doesn't matter - it's straightforward. I've successfully printed with 0.3 mm. Nozzle size is crucial, however; I'm printing with a 0.4 nozzle. While I'd love to try a 0.6 nozzle, I think it would mess up the measurements. I've printed too many already to switch now. The placeholder tile - no outside connectors but top connectors that mimic other tiles' sides. As shown in the picture, this placeholder can be inserted between other tiles and offers a grip for a further tile that can be placed on top. It's not ideal, it's not attractive, but it works. I'm open to suggestions.
