V2 GB selector plate for Retro Arms split GB and Raven HPA engine

thingiverse

AIRSOFT TOY! This is a V2 gearbox selector plate, designed to fit the Retro Arms split gearbox. It is primarily designed to be used with a Raven HPA engine so there is a place to glue to magnet in. You can order spare neodymium 5x1 magnets here: https://www.aliexpress.com/item/32961516979.html The selector plate has cutouts to have a springy fit, and minimal movement in the gearbox slots, so you can reliably use the Raven 5 position selector feature. Cutouts have rounded corners for stress distribution so it should be a while until they break off. Original POM CNC selector plate from Retro Arms is good, but it wobbles inside the rails and you get a false readings on 5 position selector feature. Original 3D printed selector plate which comes with Raven is on the other hand too tight in the retro arms gb slots. First insertion may be a little rough, little bit of material will be removed by gearbox metal slots, after that it is a snug fit. You can use some sort of plastic friendly grease on the parts where the selector plate is riding in the gearbox slots. Recommend to print with low layer height (i printed at 0.12) and at 100& infill. Also if you are using CURA you can enable ironing to have a smoother finish. Don't forget to tick OFF the option "Iron Only Highest Layer", so it will iron all the vertical surfaces (the parts where the plate rides in the slots) not only the top.
