Additional advice.
1. Bearings in Malaysia is very expensive especially those small bearing.its cheaper to get from china and replace as they wear.
2. Screw and nuts.Shops that I visit call Hex screw as capped screw. There's 3 type of screw and nuts. Steel(refer to black) which will rust. Galvanised steel(white) will not rust but not available for all size/length. Stainless steel have all size,but some size can be very expensive like m3 50mm is double the price of m3 40mm.
How about using aluminium profile ? Probably cheaper and more rigid and stable.
There is many china bearing in local. There are cheap. For slow moving speed, it should be alright to use. How small the bearing require on 3d printer? Less than 10mm diameter? Some Japan brand bearing like NSK should be cheap.
The black cap screw are not easily rust. It been treat with chemical to resistance better on rust. That's why it black. Using indoor is no problem at all. Cheaper too.
You can galvanized the screw you want or chrome it. But will cost few cent more. Comeback collect later. Most of the shop can do it.
SS screw mainly for use on corrode environment. SS are more soft and less strength. Expensive also. Avoid to use if possible.
