Version 3
In this version, the Nose Gear Mounting Framework has been simplified and lightened by removing much of the forward structure. After completing the load simulations on version 2, it was clear there were no significant loads on forward structure and could be removed as shown below. This also reduced the print time of the framework as well.
Nothing But Problems 😒
In theory, this version of the nose gear framework should have been a great mechanical solutions for a single completed assembly installation. Printing it, however, proved to be another story. The vertical towers which support the trunnion begin to wobbled from the 3D printers movement as it lays down a new layer. Being only 2mm thick, it’s just not sturdy enough to stay rigid the further away from the build plate the print went.
Needless to say, this design idea has been exhausted and scrapped in favor of a modular design. See Version 4 below.
