Hộp hút ẩm Gridfinity có thể xếp chồng (Stackable Drybox)

The original model is a great silica gel container. I have printed quite a few of them and are in use. One issue I found is the missing capability of stacking multiple of them.

So I made a remix based on the original model's STEP file in onshape. I added the stacking lip. To give clearance to the lid, the stacking lip is only the 4 corners. 

The original bin is not actually a round girdfinity height unit. So I shorten it slightly to be 6U tall, so you can stack it with other standard bins as well.

Also a new tool is needed to reach down to the lid while avoiding the stacking lip. I made the tool a 3-wing hand nut style. 3-wine so at any time, there is always one of them not aligned on the corner and have more grip-able space (other wise it's kinda covered by the stacking lip). The lid was from my other remix with a see through window . It's the same size as original and interchange-able. so as the tool.

I have made both remix on the same onshape file. As usual, onshape link here . The uploaded 3MF and STEP are assembitly state directly from the model, you'll need to place the lid and tool onto yourself.

If you have request for tiny changes, I can try to make it for you (6-wing tool ? )
