Simple Microphone Pop-Filter

thingiverse

This is a straightforward pop-filter for your microphone. This is the component you insert between the mic and your mouth. Its purpose is to transform turbulent airflow from your mouth into a smooth flow which will gently strike the membrane of the mic, yielding better audio quality. I have created mine using natural-colored PLA material, with 50% infill and a layer height of 0.3mm. Unfortunately, I did not configure my G-code correctly, so I was unable to insert the nuts into their receptacles. Despite this issue, it still functions properly. To compensate for the problem, I had to use longer screws. The required fasteners are two M3x14 screws with nylon nuts (used for securing the cable clamp, described below) and one M3x20 screw with a standard nut (or an M3x25 screw with a nylon nut if the regular nut cannot fit into its receptacle). I have utilized an old sock as a membrane, inserting it between the two circular components. You can achieve excellent results by cutting women's socks in two layers to match this design and stretching them to their full capacity. To secure the pop-filter to your microphone frame, use a plumbing clamp or a zip-tie (or even duct tape) along with a large AWG cable or a stick of some sort. The 3D-printed component features a built-in clasp for holding the cable/stick in place. Update: Following my experiences during assembly, I have made some improvements to the pop-filter design. The new version is called "PopFilter-110mm-Improved" and has enlarged screw holes, improved nut-traps, a reduced inner diameter of the outer ring (the clamping circle) for enhanced tightness, and an oval-shaped hole for the M3 nut-trap screw. You can see pictures of both the original and updated designs below. Pictures Update #2: As shown in these images, I have secured my pop-filter using a clothes hanger's metal wire to one side of the filter and large zip-ties attached directly to my microphone tripod.
