Face Shield For SMALL 3D Printers

Hello Everyone, I've revised the last update for both two-piece and one-piece designs. I've added a hole and button on the frame where the film slides into the slits. Once the film is in place, I squeeze the frame with the hole and button sandwiching it, creating a dimple-like impression that prevents the shield from shifting out of position and keeps it securely locked in place. The previous design was adequate but relied solely on minimal slit spacing and friction, this new design provides better results when squeezed. I've used pliers to adjust the larger opening option, which leaves just enough space between the jaws not to crush the frame while squeezing the film between the hole and button. This approach also saves your fingers from getting pinched. I've tested this updated version on prints from an Ultimaker 3, TAZ 6, and Flashforge, and all have shown improved film retention compared to the previous iteration. Additionally, I've lengthened the snap hook slightly to prevent breakage during assembly. Although assembly worked well in the previous version, some snap hooks began breaking when loading a new filament roll. Lengthening the snap hooks appears to have resolved this issue without compromising the security of the two halves being held together. If you're experiencing broken snap hooks, I've included a part file for a clip that can be used as an alternative fastener. The file includes STL, STEP, and IGES formats, and printing two clips took only three minutes. The file name is "FSP-R4 Center Bar Fastening Clip". I recently designed a face mask holder; if you're interested, here's the link: Face Mask Holder. Stay safe, and I wish you all continued good health. Miguel
