SKD Beretta M92 upgrade spacer/ packing

thingiverse

6mm spacer for the SKD Beretta M92 gel blaster. This works similar to the Nerf penny trick, by adding more tension to the firing spring. I've fired a few hundred rounds with this upgrade and it has noticeably increased the number of Hertz doughnuts. I printed in PLA Flex to absorb some shock on the internal components. I don't feel the material should matter much. This was inspired by the knowledge of @Cruise from gelblasterforum.com.au (https://forum.gelblasterforum.com/t/skd-m92-spring-upgrades-and-180fps/3841) Steps to install: <ol> <li>Print with flat side on the build plate</li> <li>(YELLOW) Push out locking block pin</li> <li>Remove slide by sliding forward and lifting</li> <li>(RED) Remove piston spring and piston</li> <li>(BLUE) Insert spacer between the piston and spring (flat end of the spacer on the spring side)</li> <li>Reassemble the M92</li> </ol> Please leave a comment if you have any feedback or projectile speed measurements.
