3-inch LOC Precision Avionics Bay Bulkhead. 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.
Components I use:
- 4-40 threaded rods for the e-match terminals
- 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.
- My 3D printed nuts - https://www.printables.com/model/267924-avionics-bay-terminal-threaded-nut-for-4-40
- Also need 4-40 nuts to hold the 4-40 threaded rods in place.
- 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.
- ¼-20 Lock Nuts/nuts/wing nuts
- Lock washers and fender washers
- Eye Bolts
- Charge well hole is 4-40 which will thread into the plastic.

- Connectors used - https://smile.amazon.com/gp/product/B0188IN930/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
- All of my bulkheads use the same male connectors. AV sled uses female connectors.
I have all of my 3+ inch diameter rockets using the same avionics sled, which is linked below.

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.
PLA or PETG work just fine.
