I have quite deep drawers in my shop, and I hate it to waste alot of space, so this gridfinity-bin is for a dremel 3000 series and is stackable. It spans over 2x6 gridfinity units, but there is also a split-version for smaller/regular-sized printers. The model has magnet-options for the “gridfinity refined” style, but if you don't like them, use “gridfinity rebased” to change them. 

The split version has a splint, that has a slot, so if your fitment is too lose, you can either just scale up the splint, or use a wedge like the woodworkers do. However, in my case the model has had a perfect friction fit, no need for glue, and a very stable joint. 

The model has also some ~3.2 mm-holes. They can be used to store regular dremel-tools or to mount some kind of clip for accessories or a mounting for the powerplug. In my case this was unneeded, as I store my dremel tools in dedicated gridfinity-bins.

It goes well together with my gridfinity bins for various dremel tools.

Caution: From the pictures you can see, that this is (obviously) designed for the EU-Version of the Dremel 3000 series. If your dremel has another kind of Powerplug, you have to judge from the images, if it still will be stackable then. It obviously will fit the dremel still fine, but the EU plug is reasonably flat, so that it can happily can be cramed into the remaining space, but if your plug is significantly bigger, the tray might not be stackable (at least not over the full length). However, have a look at the comment section. Someone with a different Power-plug (US-Style i guess) has printed this one, and it also seems to fit fine. Your mileage may vary.
