Parametric Propeller Guard

thingiverse

This OpenSCAD script originated as a design intended for T4 series multirotors, however I broadened its scope by incorporating additional parameters to accommodate diverse motor-mount and arm angles. A customizer was initially considered but ultimately dismissed due to complexity concerns. To begin with the instructions: The creations are manufactured using 30% infill with no supports, resulting in robust and lightweight constructions. Thoughtful comments were embedded within the code to facilitate comprehension. Visualizing a diagram illustrating parameter correlations would greatly enhance understanding; I aim to incorporate this feature soon. Disregarding the rotate([0,0,45]) directive for now, envision the multirotor's arm extending along the X axis. Ang_offset specifies the angle formed between the screw-hole slots and the X axis. Arm_ang_1 through arm_ang_3 represent the angles of the three arms relative to the X axis; keep in mind that positive values correspond to counter-clockwise rotation. Vent slots are intentionally designed to mirror those on T4 arms, yet can be omitted by setting do_vent_holes to 0. The rotate([0,0,45]) directive was initially applied to optimize print alignment within a square build bed's constraints; feel free to adjust or remove it as desired.
