Brass knuckles that wont let you down!! - the boss knuckles!!

I need your help please. if you print these you will notice an abnormality on the front between the knuckles..how can i fix this issue.or if you can and are successful please send me the file and i will give you due credit in the discription..thanks guys (= these knuckles are very strong when abs is used i have spent many many hrs testing and developing them they are still a work in progress (so they keep getting better) Thet aremore comfortable and stronger than original design. Still the original is the best i could find on thingaverse Pryor to my revamp. cheers Willrook!!! who posted the originals that i have been developing .. I think they are probably a size medium as is. I recommend doing first print 10% infill to size check and then adjust accordingly! and then PRINT AT 100% INFILL. -----(IMPORTANT)----Remember you could very easily kill someone with these!!! so use only for self defense!!!!!!!! OR BETTER YET NOT AT ALL AND USE AS A DECORATION!!!!! dont be a squid!
