star knob for 1/4-20 bolt

thingiverse

Designed to securely fasten a 1/4-20 bolt in place, this human-sized mechanism excels at adding a knob to various projects. Ideal for applications requiring a secure grip, it works seamlessly with most printing configurations. Printing supports can be done successfully from either direction without significant complications arising. However, removing these supports is notably easier when the bottom cylinder of the star-shaped knob rests on the printer bed and supports are printed for the rest of the part. This approach minimizes plastic usage but may prove challenging to remove from the finished product.
