Airsoft 3d print Impact test

this test is an attempt to standardise impact testing for 3d printed
airsoft materials, it is not an absolute test, infil and shape will still
have a far greater impact on its ability to survive without damage however
it will allow for the comparison between materials in the same geometry,

the sample is constrained at both ends, this is to prevent the leverage
from failing the part at the base, the part should be printed at 100% infil
(if trying to compare against other materials) or at your desired wall
count if testing your own print settings, the print results will be
orientation dependant and so be sure to test in both orientations and to
take note of results for each. once printed the testing process is to
place the parteither inside a vice clamped just enough to prevent slipping
or placed rear side down on a table, then with eye pro and face pro on
(if the print doesnt fail it WILL ricochet and hit you in the face) shoot one .25g
bb into the sample section
