AIRSOFT TOY! This is a V2 gearbox selector plate, designed specifically for the Retro Arms split gearbox. It's primarily engineered to work seamlessly with a Raven HPA engine, featuring a spot to glue in a magnet.

The rounded corners of these cutouts provide stress distribution, guaranteeing they won't break off anytime soon. While the original POM CNC selector plate from Retro Arms is good, it tends to wobble inside the rails, resulting in false readings on the 5-position selector feature. On the other hand, the original 3D printed selector plate included with the Raven is too tight for the retro arms gearbox slots. The first insertion may require a bit of effort, as some material will be removed by the gearbox metal slots. However, after that, it's a snug fit. Applying plastic-friendly grease to the parts where the selector plate rides in the gearbox slots can make all the difference. To achieve optimal results, print with a low layer height (I printed at 0.12) and set the infill to 100%. If you're using CURA, enable ironing for a smoother finish, but be sure to uncheck the option "Iron Only Highest Layer" so that it irons all vertical surfaces – not just the top.
