Joshua Van Vleet inspired a hex sleeve but the .stl failed and seems to failed for a few others. Never done a remix or created a 3D object before So I went to 3D builder, extruded a hexagon to the same length as Joshua's. and deleted a 25.2mm hole.

I have only got as far as printing the trigger parts and this sleeve. It fits my 25mm tube perfectly, the heavy scratching is from extreme sanding because I havn't quite mastered my Ender 5. I have no idea how it will look on the final model or even if I will use it, i'll let you know. But I made it, so i'm sharing it.
