Birthday cake numbers with a hole on top to stick a birthday candle in.
The numbers itself are ~60mm tall and the holder is another ~15mm that goes into the cake.
The hole for the candle is quite tight for the classic colorful birthday candles and grants a good stability even without extra wax/glue. I recommend putting the candle in before placing it on the cake to avoid having wax on the cake.
Prints easy and fast without support.
Even 0,3 layer and 10% infill printed in PLA worked fine for me.
For best results, you should print multi-color, yet you can also just paint the top with permanent ink.
If you want to save material, you can cut the numbers laying flat by up to 8mm from the bottom.
Thick version looks best imo though.
Took the remixed model as inspiration, yet designed from scratch.
