This is a printable version of the low poly blåhaj model by IsabelleDotJpeg (link below, model is CC-BY, please attribute her, not me). Printing it on its front end allows it to print with only two supports and almost no infill. It came out beautifully in translucent PETG.

I'm including both a large and a small one, in theory the A1 mini build plate could fit 36 of it if you arrange them carefully, but the most I've done is nine. The large one is scaled to fully use up the A1 mini's build volume.
