Rubber powered model airplane nose block

thingiverse

This is a nose block for rubber powered free flight models, designed for use with carved or plastic props. It should prove useful in many types of rubber powered models up to the P-30 class. The base design measures one inch square at the base, and assumes that the fuselage tops and sides are made from 1/8 inch material. Consequently, the part that fits inside is three-quarters of an inch square. For optimal results, it's best printed with a single layer to minimize weight, and can be easily scaled up or down using your slicer software (I used Cura 2.6).
