Version of the Gridfinity window bins modified to:
Caps stay in place decently, but a little superglue on the seam will lock it in. Included a tall cap if you don't want to use two slides for the tall bins.
For reference, the slides I've used are 25mm x 75mm x 1mm. That should be standard, but obviously variances occur.
Combined .step & f3d file for your remixing pleasure or if you want to chase tolerances.
Edit 2/22/23: Turns out the slides I have were a bit off of the standard size. Uploaded new models of the caps to hopefully allow more vertical clearance.
The author marked this model as their own original creation.
