Self developed kit to adapt the new Nerf N-series Sprinter to a half dart capable blaster.

Two versions of the Mag adapter are included, one with a support piece in the mag release detent, one without, some tweaking may be required in the slicer to get a clean support for the overhang.
The Mag release should probably be printed with a higher infill to prevent flexing, I went with 50% and seems fine.
The only additional hardware needed is 1 m3 *18 screw for the mag release. You can reuse the spring from the original mag release by sliding it in the hole in the back of the magwell once the release is installed.
In the Stock magwell are 2 thin walls that protrude to release the dart holder tabs in the original mag, In the end I've elected to just trim these down to fit the magwell in.

The Magwell lock piece simply friction fits into the slot in the back of the magwell and into the existing mag release slot in the sprinter, while the Mag release filler closes up the old mag release hole at the bottom.

Flywheel Cage 42.5mm crush, needs supports but I would reccomend setting them up such that they don't go into the screw holes unless you want to fiddle around digging them out
The cage is two parts, for less overhangs, although it probably doesn't need the filler piece it's there if you want it.

Dart Guide is a simple drop in replacement piece for the one already in, simply unscrew it and put the new one in it's place,

Pusher Extension; the end should be trimmed off flush so that the new pusher extension can be slid in on top and glued in place. I printed it 100% infill flat on the end so that it prints straight up.

Barrel Extension: to fill the gap between the cage exit and the stock "barrel" piece. I however had a spare barrel part from an old stryfe which I used.

Print orientations should be good (maybe :) )

Changes: Shortend the pusher extension and lowered the dart guide arch to reduce darts getting pulled back in, added latest .step version.

Should now be useable, have tested it for a day's worth of games and held up fairly well, more testing to be done though.
