Old guitar tuning pegs

My mom had an old guitar from when she was in college. She got it at Sears, and it probably cost about $100, and it isn't too fancy. Last week I pulled it out of our basement because I'm going to camp this summer and I don't want to take a super expensive guitar to camp in case something happens. Unfortunately, when I pulled the guitar out of the basement, the strings were either rusted or missing, and some of the tuning pegs broke off. I can replace the strings, but before I can do that, I need new tuning pegs. I have a 3D printer, so I just designed them. I also added the string names because I always forget them. I don't know how compatible this is with other guitars because this is kind of a unique guitar despite it being so cheap, and the letters will more than likely be upside down on most guitars. Enjoy!
