I printed the Original model at 0.2mm layer height and did a filament swap on layer 2 from white to black. The nose is printed at 0.2mm layer height to match the original model and is a pressure fit into teh original's nose.
The author remixed this model.
I made a nose insert that pressure fits into MaxT's Reindeer Christmas tree decoration to turn him into Rudolf.
I printed mine at 100% , but depending on the filament brand, you may get more ore less expansion and find the nose is not a tight fit. It may be best to test with 100%, 101% and 102% scaling for the X-Y axis to make sure you get a tight fit - otherwise a dab of glue will sort it.
