Face Shield For SMALL 3D Printers

grabcad

Hello All,I've changed the last revision again for both the two piece and the one piece. I've added a hole and button on the frame where the film slides into the slits. After sliding the film in the slits, I squeeze the frame where the hole and button sandwich the film, leaving a dimple like impression on the film, which prevents the shield from sliding out of position and keeping it securely in place. The previous design was ok but relied on the minimal spacing of the slit and friction, this design if squeezed does a better job. I've taken my pliers and set the pliers at the larger opening option, this is just the right amount of space between the jaws to not crush the frame when squeezing the film between the hole and button. Using the pliers saves your fingers from the squeezing. I've tested this on parts printed on an Ultimaker 3, TAZ 6, and Flashforge and they all seem to hold the film better than the previous iteration.I also lengthened the snap hook slightly to prevent the hooks from breaking during assembly. Assembly went very well on the previous iteration but when I loaded a new roll of filament, some snap hooks began to break. Lengthening the snap hooks seems to have cured the breaking issue during assembly without sacrificing the security of the two halves being held together. If you are having snap hooks break, I've included a part file, stl, step, and igs of a clip that can be used to fasten the two halves together. It took only 3 minutes to print two of the fastening clips. File name is "FSP-R4 Center Bar Fastening Clip".I recently designed a face mask holder, here is a link if that interests you:Face Mask HolderAs always, stay safe and I wish you all continued good health.Miguel
