Flite Test Spar Caps

I designed these as a less invasive way to mount the vertical stabilizer spars to various models. They're 14mm x 14mm footprint and are sized for 3mm carbon fiber tubes but will work great with bamboo skewers as well, just do the math and scale up accordingly. I've made them from PLA, PETG, and ABS. All are plenty strong for their purpose. You can even scale up bigger to make some sleek wing spars with larger diameter tubes. I recommend printing on a rough textured plate for better glue bonding. 100% infill so set wall and surface count to whatever you want.
