Avionics sled that will fit in 38+mm airframe tubes. Included adapter is needed for 3+ inch diameter rockets.

Altus Metrum EasyMini x2- https://altusmetrum.org/EasyMini/
Battery 400 mAh x2 LiPO - https://shop.gag.com/parts/400mah-lipo-battery.html
Connectors Used - https://smile.amazon.com/gp/product/B0188IN930/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
- I like these connectors because they lock into place. I also hot glue the wire and connector.
Sled is made for #10-32\" threaded rod
Adapter adapts the sled from #10 to \u00bc inch threaded rod. It is compatible with LOC precision 3in avionics bay bulkheads. (that's what all of my bulkheads are based on)

Printing sled with PLA or PETG at 0.2mm layer height will work well. The adapter is good at layer height 0.3mm using PLA or PETG.

No supports needed for the sled or adapter.
