Hi Bambus...
i had a 2040 Extrusion as leftover and created this VAT Stand.
I remixed a few things from Thingyverse:
Base: https://www.thingiverse.com/thing:4461630
Holder: https://www.thingiverse.com/thing:4172070
Funnel-Hoder: https://www.thingiverse.com/thing:3925160
The Extrusion is about 36 cm long.
The funnel is from Amazon or Ali (https://www.amazon.de/gp/product/B08CKS459Q/ref=ppx_yo_dt_b_asin_title_o05_s01?ie=UTF8&psc=1)
