Since I couldn't find any + symbols for my project for 3d modeling, I was very stressed and almost late to making the 3d model for my schedule. Luckily, I was able to make the 3d model myself. I think it is stupid that people are selling these for money, so I'm selling this for free. Hope you enjoy!

INSTRUCTIONS:

3D Printing is the best way to do this. Just use really any material, PLA is what I use. Infill density is 50% or higher recommended for best strength. Don't know how to do laser cutting though.
