I found a speedloader mod for my Nerf Rival Kronos and looked at some of the pieces. there were 2 Major problems

first the door replacement piece needed supports BUT you didn't need the part of the piece that made it need supports (if that makes any sense) so I cut that off

second almost every piece was flipped upside down (making it harder to print) WHY?!? I have no idea but I fixed that as well

I will upload lots of pictures of how this works and how to put it together after I make this which will probably be in a day or 2 but for now, you should be able to figure everything out on your own

ALSO

I am planning in the near future make this into a print-in-place design so there won't be so many pieces AND I will add the 6 round tube but for now, I will keep it as this.

so STAY TUNED and don't forget to post all your awesome makes!!!!! -GV

UPDATE 7-2-18

I was printing this myself and the door replacement piece would always slice WITHOUT the hole in it!!! I fixed the problem and I uploaded the second piece named "door replacement piece FIXED" hope this helps tell me if there are any other problems and I will fix them right away!

STAY TUNED -GV
