Hi, can you design it for cutting for Gola profiles on top of wood plate and for drawers?

I think this has some design / tolerance issues. First, the radius on the plates do not come out even with the side guides that orient the assembly on the board, as a result, the router will cut a radius that is slightly 'pushed in' to the corner, resulting in a small indent step where the radius starts. I guessing this slight misalignment was done to allow the radius guide to snap into the holder without binding, but that gets into a basic design issue: Its just not possible to get 4 posts and their holes to be perfectly aligned, let alone align with the side guides so it all comes out perfectly. If I were designing this, I would reduce it down to a single pin that protrudes from the holder. The pin would not be round, but rather slightly blade shaped to only provide orientation to shove the guild into the corner it should seat into. Even that blade should have a slight bit of give to it, since it will need to allow a slight be of accommodation for slight dimensional variation. This type of approach (bladed style pin / keeping track of how many positional constraints, etc.) is common practice in fixturing. For an example of a 'bladed' locating pin, here is one sold for the purpose so that it locates in only one direction: https://www.mcmaster.com/products/fixture-pins/locating-pins-1~/ (In this catalog they call them diamond pins)

plates were pretty tight on the pins even after a thorough deburring.

This has tolerance and alignment issues. See my other comment.
