Hello I hope it's ok to share a little rig I've been toying with lately. The goal has been to find a lightweight and inexpensive solution mainly for simple soundscapes when I'm travelling. The mics are the Immersive Soundscape's Thumb omnis which seem really well built around Neutrik connectors. I have two recorders, a trusty R-26 and a MixPre 6 II which I recently got.
Clamps These are from Stagg (4,50 Eur) —

I will however add some padding inside to make them close around the mics better. Out of the box they won't allow dipping horizontally like on the photos but the plastic is not too tough and can easily be cut to make the arm swing lower. They have 3/8 holes so need an adapter ring to fit on the bar. Being a photographer I tend to have such stuff in droves, but a good pack to get is this one with various connectors and adapters —

Bar This is by Utebit (10 Eur) —
https://www.amazon.nl/-/en/dp/B08NSX1R5ZThis is actually a photography flash bracket, but I like that it is extremely light and has four proper and easily adjustable tripod screws plus both a standard 1/4 inch tripod screw and a larger 3/8 inch screw. It's 30cm long.
Tripod This is my old carbon fiber Rollei C5i (around 130 Eur) —
https://www.rollei.de/products/carbon-stativ-c5iThis is my main travel tripod which has been with me everywhere. I like that it functions as a proper full-height tripod and can hold fairly heavy cameras (think medium format camera with large wide angle) yet still fits into a carry-on and only weighs 1,2kg.
Not on the picture are these magnets —
