A couple printed widgets

well, that printed well out of the gate with a nice fit. strong grip on the clamp end. time for some drop testing. I am going for a 10 foot drop. that should do it.

OUDEW canopy breaker mount successfully tested to 40g in all orientations in sequential testing except upwards, as that orientation was difficult to set up. Testing to 24g was straightforward, but achieving 40g required mount design and print-style adjustments. The 40g test involved a 10-foot (120-inch) drop onto 3 inches of foam. 120 drop distance/3 stopping distance = 40g. Guides were used at the top to ensure a straight drop, and a lanyard string helped contain any subsequent bounces. I can only estimate the upwards g capability at this time, but I believe it could meet 24g.

I am currently evaluating optimal cockpit placement for the canopy breaker mount.

I've decided to remove the OUDEW lettering on the printed mount in the future. The lettering was scratching the backs of my fingers. At least I learned something from the testing!

After considering canopy breaker placement, I located it near where canopy breakage would likely be needed. Given the likely orientation of being upside down, I oriented the removal direction downwards, so it will be upwards when upside down. I removed two other canopy breakers from the aircraft for a net weight savings.

The canopy breaker mount I used was the same 40g test specimen because it was in excellent condition.

Fuel sump drain plunger... I've been using this one for the past four years without issue. Recently, I needed to drain a couple of quarts to clear a weeping sump and wondered if larger ears would be beneficial, so I enlarged them and will be conducting a test.

It's really convenient to print parts because you can easily modify an existing design, get good parts with the changes, and have them ready for testing quickly.

I had a feeling I would like it, and I definitely do. I drained 1/2 quart with almost no effort. It gets the prestigious cockpit location.
