Costs just a fraction of the “real” thing. Worth its weight in gold as a diving toy, whether in the bathtub or in the pool...
Print with 100% infill, 0.4 nozzle and 0.2 layer height.
If you use a smaller nozzle you can scale down proportionately without losing detail in the engraving. (0.3 > 75% / 0.2 > 50%). Sinks steadily to the bottom like a real coin and is easy to spot.
Print 2 halves and the alignment block and glue them together. With the alignment block you can orient in such way that the logo can be tilted horizontally or vertically.
Printed in Prusa PLA Viva La Bronze.
