Nerf Rival Kronos Speed Loader

I remixed the Speedloaders. While I did like the original ones uploaded here, they lacked something in the open end of the housing to stop the balls from potentially falling out.
I therefore remixed the housing to add little brackets on the open end, small enough not to damage the balls or stop them from easily moving through, but big enough so they can not just fall out.
I also remixed the Slider, so it can move past those brackets I put into the housing, by cutting into the stem a bit. I also made the openings all over the slidder a little bigger so the print tolerances are now slightly better and it will generally fit into the housing just fine. I left the end cap as it was as I can't think of anything to improve on it.
As these are meant to be used with my own Jam Door replacement I also shortened the housing a little bit. and to make printing the housing a bit easier standing up I made the lower part completely circular instead of keeping it hexagonal.
