Front air deflectors for Voron 2.4 350mm bed printer.  Tested on 350mm LDO Rev. D.  kit with kinematic bed mounts, Nevermore filter and Z axis guards installed. The model can can be completely customized by editing the OpenSCAD file for different bed sizes and alternative bed/accessory configurations.  See https://www.printables.com/model/1613243-voron-24-under-bed-chamber-heater-5015-blower-fan for angled 5015 fan mounts.

You will need 4x M3x8mm screws and 4x T-nuts in addition to the printed parts for installation

Print with layer height of 0.2mm/layer, set layer height to 0.1mm from h=2mm to h=3.4mm for a smooth finish with default settings, change if the shape is altered.

Note: you will need the two SVG files originally from https://github.com/VoronDesign/Voron-Extras/blob/main/Images/Logo/SVG/Stripes_Logo.svg and https://github.com/VoronDesign/Voron-Extras/blob/main/Images/Logo/SVG/Hex_Logo.svg , both files with a GPL 3.0 license.  Put these in the same directory as the .scad file and rename them to "VoronStripes_Logo.svg" and "VoronHex_Logo.svg" respectively to make them work.  Or just download them as attached where they are already named correctly.
