Diamond paste syringes holder

I never really use any diamond paste as it all sits in a bag but today I was polishing something up and thought to myself let's see how these work. I quite liked them so I decided to make a wee stand for them so I can actually see them around and always have them on hand.It holds 12 syringes as I had 12 and two 2-inch felt wheels as that is what I have on my polisher if anyone has some idea for what would work better feel free to tell me or do tell me any advice is appreciated.As with most of my tools now I printed it hollow with no bottom layer and poured in some Jesmonite or maybe even just plaster this time to give it some weight and then added a sheet of EVA foam so to protect my work surface.
