The part was missing, so I designed it in CAD since I couldn't find a part number for it.

V1: Initially, I messed up the CAD file and couldn’t add the small friction features on the outside. It’s a bit loose, but once you put it on the drawer, it press-fits the parts together quite nicely.

It prints alright with a 0.6 nozzle.

V2: I updated the design to include the friction features, but I haven’t tested this version yet because V1 ended up working well.

To print the small features, you have to use a 0.2 mm nozzle.
