My impact socket set came with a metal socket rail, that I find unhelpful when I want to use my sockets directly from my tool chest. This 3D print provides a tray that my sockets sit in. The sockets are easy to get out and to replace. Each socket hole has an adjacent socket size label making size selection even easier.

I've included a 3mf file for a two colour print on a Bambu Lab with AMS for Bambu Slicer. You could also do a filament colour swap near the end so that the raised text is printed in another colour and make it more visible. The filament colour swap is setup in your slicer software. Setting up the filament colour is easy in Bambu Slicer, other slicers probably, too.

This socket tray matches my 10 piece Kinchrome 3/8" Metric Deep Impact Socket Rail set. See https://www.kincrome.com.au/10p-deep-imp-skt-set-3-8dr-met

Due to the overall length of the socket tray, which is bigger than my printer print area, I've split it into two parts that tightly clip together.

My print is made with eSUN PLA+ 1.75mm black and red filaments, with 0.2mm layer height and 15% infill on a Bambu X1 Carbon printer. Wall Loops = 4.

I hope you can find this print useful, too.
