Crane Arm End

thingiverse

This marks the conclusion of a comprehensive operating crane that I have been designing. Upon completion, it will reach an impressive height of approximately three feet tall. This particular component prints directly in place, allowing the pulleys to spin freely without any hindrance. The design takes inspiration from the classic Unit cranes of the 1950s, albeit with a more generic arm. Notably, the holes at the connection points have been carefully scaled to accommodate pieces made from 1.75mm filament. Future enhancements will include motorization and control via a small controller, making it an ideal tool for training purposes, particularly in hand signals and crane safety protocols. The print settings used were 20% infill with PLA material. It's essential to note that tree supporting is not recommended due to the printer's tendency to miss supports when they exceed two inches in height. Instead, wall supports should be employed, and printing flat yields satisfactory results. Once all additional components have been designed and uploaded, I will provide links for download here.
