Human: 100% 3D Printed Mask. Everything except the filter can be printed with ease. The mask boasts a replaceable filter that can be easily swapped out whenever needed. No cumbersome bolts or screws are required; simply seal the TPU mouth and nose part to the top mask part using glue, epoxy, 3M bed tape, RTV, and more. The design necessitates no supports at all. To achieve optimal results, print the mouth and nose part in TPU with a layer height of 0%. For the remaining parts, use a rigid material like PLA, ABS, or PETG. If resizing is necessary, utilize the 90% small size mask template. A STEP file is conveniently included for those who wish to modify or customize the design. -Brett
