The design of this sliding clamp was inspired by other sliding clamps I've seen. There are many manufacturers on the market offering such clamps, but as far as I know,Gripstic*

I also designed several extended-version clamping devices that can be printed horizontally. These designs have a small amount of support structures pre-installed inside, which need to be manually removed after printing is completed.
