Koolertron One Handed Macro… https://www.amazon.com/dp/B07VWHS9V6?ref=ppx_pop_mob_ap_share
– rgb lighting
– comes with cable and 2 sets of plain keycaps
– includes 9 switches
– fits in the palm of my hand
– looks 3d printed, but maybe you get what you pay for
– furthermore, there are flaws and imperfections and that are inevitable
– switches are exposed (eventually, i want a wooden casing that would be thicker and improve the appearance)
Amazon. I use the small one for streaming and recording controls. The larger one is for various in game macro commands.
