Description
This is an incredibly forgiving print. You can print it with the curved top on the bed and no supports. Or place the base on the bed and enable supports if you're concerned with bed adhesion issues.
Whatever your usual settings are should work great but I suggest at least 3 or 4 walls for strength and to make the air channel wall all walls.
FPS RANGES
Place the bottom part over the barrel and slide it down. Then place the Acorn on the barrel and twist the bottom piece in place.
Collet on first then screw the Acorn on to it. You can try and use a tiny o-ring if you need to as well.
M3 screw and nut. Depending on your tolerances it might not actually need the hardware.
The Acorn as featured on FNC got it start as a combination of a hair brain idea and some great ground work by @Midwestt. His original file is no longer published but it prompted me to use my very fledging cad skills to recreate it. After some rather successful results from mostly educated guess work I showed it to @Redcowl on the nerf discord who become an incredibly helpful and integral part of the development of the Acorn.
He let me use his collet attachment, got some incredible BCAR information from another designer (I will credit him if he wishes but I have not confirmed that yet), did the math for the FPS groupings and helped with extensive testing and even helped secure the lock and sleeve mechanism.
After months of testing and some rather funny slow motion video with to much spin on higher fps darts we had a handful of people help us test the design with incredible results that far exceeded our expectations or plans.
