3dverkstan-like protective visor with parametric forehead clearance

thingiverse

Protective visor with increased clearance, as requested by workers who value safety.\r\nDesign inspired by 3DVerkstan's innovative approach to protective gear.\r\nOnly version "Europe-888" implemented, feel free to expand on the design.\r\nKey differences and improvements:\r\nRedesigned from scratch using OpenSCAD for precision and flexibility.\r\nClearance between forehead and visor is adjustable, allowing for a customized fit.\r\nStacking capability is embedded in the design, ensuring proper support without relying on slicer settings.\r\nModular design enables customization through options like only_left_arm, only_right_arm, and only_brow.\r\nThis protective visor fits on a 200x200 build plate, with three full visors capable of fitting on a 370mm diameter AnyCubic Predator.\r\nAdjust clearance and roof_radius to suit your needs.\r\nThe "roof" is the part of the brow that rests against the forehead.\r\n"Clearance" refers to the front-to-back distance of the brow, ensuring minimal contact between forehead and screen.\r\n"Approximate_height" should be set between 5 and 6 for optimal results.\r\n"Layer_height" adjusts the actual height to a round number suitable for 3D-printing layers.\r\n"Thickness" controls the thickness of all parts.\r\n"Support_layer_count" determines the number of support layers between stacked visors, with three being a good starting point for single hotend users.\r\nThe "zig-zag" pattern forces the slicer to print support layers continuously, preventing jumps between arms and improving overall print quality.\r\nModular versions offer flexibility, with four brows fitting on a 200x200 plate (protective_visor_4_brows.stl) and up-to eight left and right arms capable of fitting on the same plate (protective_visor_8_left_8_right_arms.stl).\r\nAlternatively, print two complete sets at once for increased efficiency (protective_visor_2_modulars.stl).\r\nFiles like protective_visor_8_left_arms.stl and protective_visor_8_right_arms.stl allow for printing only left or right arms with adjusted clearance.\r\nOther STL files may require tweaking of 3D-printing parameters to avoid squirting outside the plate.
