<p>4-inch Madcow Avionics Bay Bulkhead. AV Bay for Quantum Tubing. I design my parts to be replaceable as much as I can. So, nothing is glued on my AV bays. I use lock nuts and lock washers instead.</p><p>Components I use:</p><ul><li>4-40 threaded rods for the e-match terminals<ul><li>To prevent shorting (quick link, etc. could fall across the terminals) out the terminals cover them with tape or use my 3D prints nuts made for this.<ul><li>My 3D printed nuts - <a href="https://www.printables.com/model/267924-avionics-bay-terminal-threaded-nut-for-4-40">https://www.printables.com/model/267924-avionics-bay-terminal-threaded-nut-for-4-40</a></li></ul></li><li>Also need 4-40 nuts to hold the 4-40 threaded rods in place.<ul><li><a href="https://smile.amazon.com/gp/product/B000N2YSU8/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1">https://smile.amazon.com/gp/product/B000N2YSU8/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1</a></li></ul></li></ul></li><li>¼-20 Lock Nuts/nuts/wing nuts</li><li>Lock washers and fender washers</li><li>Eye Bolts</li><li>Charge well hole is 4-40 which will thread into the plastic.<ul><li>My charge wells - <a href="https://www.printables.com/model/267864-avionics-bay-black-powder-well">https://www.printables.com/model/267864-avionics-bay-black-powder-well</a></li></ul></li><li>Connectors used - <a href="https://smile.amazon.com/gp/product/B0188IN930/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1">https://smile.amazon.com/gp/product/B0188IN930/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1</a><ul><li>All of my bulkheads use the same male connectors. AV sled uses female connectors.</li></ul></li></ul><p>I have all of my 3+ inch diameter rockets using the same avionics sled, which is linked below.</p><p><a href="https://www.printables.com/model/267822-avionics-sled-for-3in-diameter-rockets-altus-metru">https://www.printables.com/model/267822-avionics-sled-for-3in-diameter-rockets-altus-metru</a></p><p>This means I have all of my 3+ inch rockets avionics bulkheads have the same spread between the threaded rods. Which is why I have designed so many bulkheads…I have a lot of rockets.</p><p>PLA or PETG work just fine.</p>
