This is my version of Spongybob1958's Spice Rack Pullout https://www.thingiverse.com/thing:4356449 . I designed this for bags of spices as you can see in the pictures, it also can store any other bags fit similar ingredients.

This version does not need any railing, just 4 M3 screws and one M4 connecting screw.

I printed this on Ender 3 V3 SE with 15% infill and 8 line brim just to be sure.

With setting I mentioned earlier I would say it can hold up to 1kg of weight.
