I decided that I wanted to make my own with a few extra features.##__Printing__Print flat on the bed with fairly high infill for better strength.Depending on the orientation of the inserts, support may be needed. Double check the holes in the inserts are properly supported before printing.The one I printed was made with PolyLite Black PETG and PolyTerra Army Red PLA##__Parts__* 3 x M3x(KeyThickness+SpacerThickness+7mm)* 3 x M3 nut##__Assembly__Print out all the parts and spacers if desired and stack them together. Tighten the 3 screws, being careful to not overtighten the middle one and, if needed, smooth the edges.The spacers provided match the ones used in the one I printed, depending on your keys, you may need to make your own.##__Designs__Feel free to take the insert parts and add your own design to them, that was the point of having them in the first place.Design was made in solidworks, the part files for the inserts are included for easier editing if you have access to solidworks.
