Parametric knob

thingiverse

This adjustable knob is loosely inspired by marcsulf's project, specifically designed for a Lamborghini boiler - yes, they do manufacture more than just high-performance vehicles! To successfully print it without any issues, you'll likely want to turn off the handle or else you'll need to use an excessive amount of supports. It's worth noting that earlier versions of FreeCAD also included this feature. Print Settings: Printer: FlashForge Creator Pro 2016 Rafts: No Supports: No Resolution: 0.18mm Infill: 15% Notes: Protecting the boiler from heat damage requires ABS material.
