Kincrome socket tray (13336P)

So my original ratchet broke in my kincrome 13336P set, through, some abuse, i picked up a cheapy to replace it, but it was slightly larger than the original, so i cut the original tray to suit, over the years, the plastic tray became brittle, and, it evenutally broke, so i had no tray and just a bunch of tools in the box.

This was annoying as I could never find the correct sized socket, so i thought, i have a printer, this has been an issue for far too long...skip through days and days, and 10+ revisions, and bam, you have yourself a socket tray, yea its not perfect, as outlined below, but it does the job, and I am not wasting anymore filament on this.

The filament was changed out to create the text.

SO, what can you improve.

1. The 11mm and the 7/16 could be tighter, as the wavy radius around the bottom inner edge is a bit loose.

2. The universal socket and the 2" extension are a bit close, and a little difficult to remove, not quite sure how i'd fix that, maybe reduci
