This a shorter version of the 3/8 inch hair clippers guard! For short hair but not bald! It's just a shorter one of this thing: http://www.thingiverse.com/thing:34788 which is 3/8 inch. Print this little fellow out, attach it to your very own Oster 76 hair trimmers and get to work! Infill: 10-15. DO NOT exceed 40% other wise it will peel up due to cooling. even 30% may be to much. Shells:1. Any more and you will have to file the edges to make it fit. No raft. It makes the underside rough. I don't know the height on this guy but he's short! I rounded the edges like I did on the 3/8 inch guard v4.5 for the best comfort. I'd like to someday make the measurements for all of the sizes and have my very own set of printable clipper guards! Enjoy!
