RC2 Compatible Face Shield for 0.8mm Nozzle · 模型 2767

作者：Aaron Neely

***EXPERIMENTAL*** I do not yet have a proper shield to test these parts with. I've made paper mock-ups from the Prusa RC2 shield template and all of the holes line up as they should, but I can't 100% confirm this design. Primarily, I would like to confirm that the lower reinforcement snaps into place nicely on a 0.020" / 0.5mm shield. If anyone has a printer with a 0.8mm nozzle and can get their hands on a shield to test this for me, I would greatly appreciate your feedback! 2020-03-25 UPDATE: Prusa has just released their RC3 revision. See my updated remix here: https://grabcad.com/library/rc3-compatible-face-shield-for-0-8mm-nozzle-1 My goal with this RC2 remix was to take advantage of the high flow rate of large-diameter nozzles (larger than 0.4mm) to increase production speed. With this design and a print speed of 50mm/s, I can print a set of parts in ~45 minutes while maintaining the full 20mm headband height and the original Prusa strap hooks and shield mounting post layout. This design is intended to be completely cross-compatible with the original Prusa RC2 Face Shield. VARIANTS: Stiff/Flex: The stiff models have consistent 2.88mm (3 perimeters) wall thickness. The flex models have 2.88mm wall thickness for the front strap and 1.92mm (2 perimeters) wall thickness everywhere else. I find the stiff models to be more comfortable because the arms of the headband better resist the tendency of the elastic strap to apply pressure to the sides of the wearer's head with the ends of the arms. Still, the flex models print faster and with less material, so I've included them. Brim: It is a common problem to have the arms of the headband lift off the print bed during printing, so I've added a small brim to each arm to help with bed adhesion on the "Brim" models. The brim can be trimmed off with flush cutters. I use Simplify3D for slicing, so the settings below are organized as they are in Simplify's profile system. These settings should translate to any slicer, though they may be named and/or organized differently. CRITICAL PRINT SETTINGS: Extruder: Nozzle Diameter: 0.8mm Extrusion Width: 0.96mm Layer: Primary Layer Height: 0.6mm Outline/Perimeter Shells: 3 Infill: Interior Fill Percentage: 0% ;(Infill disabled) External Fill Pattern: Concentric ; UPDATED 2020-03-25, Missed this with initial upload Support: Generate Support Material: disabled ;(Supports disabled) Advanced: External Thin Wall Type: Allow single extrusion walls Internal Thin ...
