Microphone Windjammer Cage

This cage is designed to be a support for additional coverings (spandex and faux fur) to reduce wind noise for any microphones mounted inside. It is printed in multiple pieces and then assembled to create the final shape. Notes about each component are listed in Print Settings.

A note about thermal inserts...

You install these using a soldering iron with adjustable heat and turning it way down. Make sure the tip is clean and stick your thermal insert on it to warm it up. While it's still on the soldering iron, press it into the hole (smaller taper goes first). Make sure its far enough in where the thermal insert is slightly below the surface of the plastic.

Material: I highly recommend you use Matterhackers PETG+Carbon Fiber. It's a bit more flexible than other brands I've tried. 3DXTECH works OK too, and is just a little more brittle. I've tried this with nylon (too soft), filled nylon (horrible shrinkage issues), and regular PETG. The best ended up being the carbon fiber filled PETG from Matterhackers. Don't let that stop you from experimenting, though : )

You'll need to pick up some additional hardware to assemble this. Namely threaded inserts and a few different kinds of screws. I've included the description and McMaster Carr part numbers below. Note that the quantities listed are how many that are used in the project and the part numbers are bags of multiple screws. Its good to have extras anyways : )

Notes:

Ends and Sides: These are printed with no solid top or bottom layer, at 25% honeycomb infill. Adjust your shells to 12 so it gives it a nice border. The sides are flexible enough to be bent even though they're printed flat.

Top and Bottom Clip: Print this normally, with 2 or 3 solid top and bottom layers. Use 4 shells, as it will provide a good solid hole for the thermal inserts to go in. The thermal inserts go inside the channel, and then in the 4 holes on the bottom clip on the other side. These will be used to mount other stuff inside the cage.

Tripod Mount: Same rules and the top and bottom clips, but you'll also need to add some support under the square part that holds the 1/4-20 threaded insert, assuming you print it with that facing up.
