Face Shield Frame 8.5x11 with 3 Hole Punch

thingiverse

I was facing a tough challenge finding a face shield frame that fit my specific needs for a standard US 3-hole punched 8.5x11 plastic film, which is commonly used in my printer. I decided to start from scratch and made significant adjustments in TinkerCAD. To begin with, I scaled down the design to accommodate the smaller bed size of my printer and reworked the shield mounting posts to ensure they were compatible with the new scale. Additionally, I removed excess material to speed up the printing process, which now takes less than 45 minutes with around 3.5 meters of filament. I also added a stacked version of the design for added functionality. The PLA prints well on my FlashForge Creator Pro and is relatively easy to separate into individual pieces once printed. However, I noticed that there are some strands left between layers that need to be cleaned up before attaching the plastic components together. For the shield itself, I used a standard US 3-hole punch for 1/4-inch holes on an A4 overhead projector slide with dimensions of 8.5x11 inches. The face shield is surprisingly comfortable and provides excellent airflow, making it a great solution for my needs.
