These modified divider bins have one wall replaced with a glass microscope slide! Glass is more scratch-resistant than acrylic, and microscope slides come pre-cut to size.
Each bin is made of two parts, the Compartment and the Faceplate. You'll also need:
- 1x3" Microscope slides: https://amzn.to/3O6qjBO
- 2mm Repair Tape: https://amzn.to/3M1D9zF
How to assemble:
- Apply two strips of tape to the microscope slides, touching the short edges.
- Stick that slide to the faceplate.
- Apply two strips of tape down the short sides of the faceplate, over the glass.
- Apply a third strip along the bottom. It will curl a little around the bottom.
- Slap that crap onto the divider bins. Press hard.
These are perfect for storing small parts, especially if you plan to stack 'em up. The big window makes it easy to check what's inside and monitor your supply levels.
The inner surface has a generous scoop to make retrieving parts easy, and the tab fits 12mm label-maker tape.
I've provided a selection of different divider counts, to give you OPTIONS! Because microscope slides are only available in one size, only 2-unit-wide bins are possible.
Brims and support are not required, and these can be printed in any filament with an 0.6mm or smaller nozzle.
Gridfinity Tips!
- All storage blocks are compatible with all baseplates!
- Most storage blocks are stackable!
- You can add 6x2mm magnets to the corners! They won't magnetize the contents.
- You can also use M3 screws in the corners.
Gridfinity was inspired by Alexandre Chappel's ModuBOX system, which is found at https://www.alch.shop/shop/assortment



















Necro post, apologies. Couldn't the whole "tape the glass" thing be avoided if the upper piece (the "hat" over the glass) were a separately printed thing that just "snaps" in? So the whole front face would be empty, but with a groove for the glass. Then the above-the-glass plastic piece would not be a flat board, but more like a "U" or "sunglasses" shape, with arms that connect to the left and right side, bracing and adding support. I've tried like every remix...
Couldn't you move the Gridfinity tiles from the bottom of the bin to the back. Leaving the glass on the front and opening on the top. This would allow you to wall mount it with Neodynium Magnets, also with tabs on the front to allow you to grab the box and pull it off. Maybe later add a simple slide lid that would stop it from spilling if someone knocks it off the wall. I am still trying to figure out 3D modeling software so I dont know how to do it (lol), but had the idea.
Wouldn't it be better to have the glass window on the other side? Having to flip the container around to use the finger digging ramp seems counterintuitive.
did you think about this for 2 seconds? how would you have the glass on the finger ramp side... fella...
Did you?

for great tape get "3M VHB RP16" its 0.016 [in] thick foam tape with fantastic adhesive! ...you can get it from McMaster Carr, MSC, Grainer, Zoro, etc.
if you need thicker take get a higher RP number
It didn't seem like the electronics tape was going to be enough so for extra sturdiness, I just passed a woodburner at 220C over the seams between the box and the faceplate.
Here is an idea though - the tape could be done away with entirely if instead of a separate faceplate, there was a slot to drop the glass into, and then a cover piece for the top of the slot.
I made this remix! Works incredibly well with no tape, just two drops of superglue to hold the "faceplate" in place. Try it out and let me know what you think! https://thangs.com/designer/smith.matthew/3d-model/Gridfinity%20Window%20Divider%20with%20rails%20-%20no%20tape-73567?manualModelView=true
I have built my first few window dividers and came to the same conclusion. To slot in the glass would be way easier, especially if you need them in masses. Great idea!
I'm not impressed with the strength of the adhesive on the 2mm phone repair tape linked. Even when being very careful with clean surfaces/tweezers it seems like the boxes come apart with very little pressure.
Anyone find a 2mm repair tape they like?
Update: If you add 4 drops of super glue to the faceplate before putting the pieces together (along with the tape) the integrity is greatly improved and would take a lot of force to separate.
I used links to order the glass slides and they are roughly .5mm too long. Verified part dimensions with calipers so maybe the slide guys don't have as much accuracy in their length. I'm using fine emery cloth to sand the ends down (one at a time). I suppose I should just edit the model. Thanks for the system.
The slides fit fine for me, but my dimensional accuracy might be off (printing slightly too large) Tolerances are tight on this model.
I run a deburring tool down the sides where it mounts and they fit fine
Are the 2, 4, and 5 compartment window box stl files supposed to have the faceplate merged into each model? I'm assuming not since there is a dedicated faceplate stl file to print separately. Can you fix this when you have a chance, Zack? Awesome video on the Gridfinity system btw!
I accidentally exported them without adding the Faceplate cutout! I’ll fix this ASAP - sorry if I wasted your filament!
I ended up fixing the 2 4 and 5 models and uploaded them here just trying to help out until Zack notices/fixes these problems.
