Important: Verify that there's clearance between the altimeter and all thread, or you'll risk shorting it. Ask me how I know this.... A couple of nylon washers beneath the mounting holes of the altimeter will provide sufficient clearance to ensure safety while still fitting in the tube. - Edit: This issue has been resolved with an update published on 5/16/17 Run a single piece of M6 all-thread through the bay, with a forged eye nut threaded to each end. This will securely hold the bulkheads in place and provide a safe spot to attach shock cords. I plan to drill a hole in the all-thread to insert a cotter pin, preventing the eye nut from backing off during flight. This design includes a mount for an Atlas Metrum EasyMini dual deploy altimeter. The EasyMini is available at https://altusmetrum.org/EasyMini/ The flight computer and ematches are powered by two 1000mah 3.7V batteries, wired in series to bring the voltage to 7.4V. These batteries can be found at https://hobbyking.com/en_us/turnigy-nano-tech-1000mah-1s-15c-round-cell.html The total weight of the print (including 4.5g for the Easy Mini and 20gx2 for the batteries) is x grams.
