I figured why not make the belt too. I left the belt piece as a single item but you can multiply it to however you can fit on your printer. They should all connect when they are all sized (same size for all of them) to your liking. I made a hole passage for them as well for the option to have an elastic belt thru. The hooks don't connect to each other, I left that part for the idea of velcro-ing those pieces onto her skirt.
My printer is currently needing some TLC so my prints in the photos are not the best example of a good print, my apologies. I do hope your print will be better than mine. I can't wait to see your print! as usual, please inform me of any issues you have with my models so I can correct them :)
