This three-blade prop uses a 1/4 inch x 20 bolt with a button hex head for the shaft. I purchased the 4-inch bolt at McMaster-Carr here: https://www.mcmaster.com/91255A532/
The shaft is held in place by a 1/4 inch x 20 nut which is pressed into the part after printing. Depending on the length of the bolt this print can be used for small mixing applications from paint and lab use to lemonade.
The three-blade prop was printed with Fluorinar-C™ Kynar® PVDF filament and turned out very nicely.
