Painting Masking Tape inner roll hub wheel

I was missing the internal wheel hubs when I bought an open-box masking tape weighted dispenser, so I made my own with both hub spacers and non-hub spacers. This is a project I did in FreeCad while learning how to apply sketches to curved surfaces, so the design is basic and a bit rough. I included plates for the three most common sizes 23mm or about 1", 36mm or about 1 ½", and 48 mm or about 2". I have plates that include sizes with and without hubs. I doubt anyone else has this type of design need; nonetheless, I thought it would be good to share here in case someone breaks or loses their hubs. If you like the work of beginning designers, I always appreciate both comments, suggestions and boosts. 

Boost MeI'm just learning basic design software and 3D printing, so I appreciate both comments from those more experienced and boosts from those who appreciate original designs and the efforts of new-to-3D designers.
