Schubox V2 - Gridfinity Storage Box

This is a gridfinity based storage box system I've developed over the last year or so called the Schubox. 

Please read the following carefully - this is a very filament intensive project and the info below can help mitigate issues that may arise. 

From August 21st-23rd 2026 this page will be under construction. I am migrating all of my files over from MakerWorld onto hear for easy access. Please be patient as things update. 

I highly suggest printing just the handle hinge and front handle first to verify pin fit or screw fit before you commit to the base & lid. 

I always make updates after publishing any project so please read the update log down below. I've created a Patreon for updates and early release files for upcoming sizes and improvements. 

What makes this storage box different?

• Gridfinity inside (Not on the top or bottom for this large model)

• One handed opening latch

• Box stands freely on back edge (vertically)

• Lid stops opening at a specific angle - does not fall all the way over

• Uses durable pins for latch and hinges 

• Integrated drawer slide features in the sides of boxes

• Has option for labels

• Boxes can stack & latch together for carrying multiple  

• Pivoting top handle for top carry 

• Pivoting front handle for front carry 

• Mounting plate that can be bolted or strapped

• Surface and undermounting plates for the drawer system

• Wall mount 

• Caster Bases

Gridfinity Specifications:

Gridfinity was started by Zack Freedman and you can learn more about the system here. 

The boxes are in three specific sizes: 5x4, 5x4, and 7x6. More coming, but if these don't meet your needs there are many other systems out there! 

Please note that the large size does not have gridfinity on the outside of the lid. 

If you print short bins - your stuff will go everywhere inside the case. If you print the appropriate bins with additional labels on top of the label shelf, they may not fit properly. My favorite bin generator is Perplexinglabs.

Materials required: 

• PETG (Ideally High Flow) or PETG CF Filament

• Standard Size Boxes (5x4, 5x5): 3dx30mm steel dowel pins. M3 Bolts are an option as well.

• Large Boxes (7x6): 4dx40mm steel dowel pins (Amazon or McMaster Carr are good US sources)

• 6dx2mm magnets optional (Press fit or glued into bottom grid)

"Can I use PLA?"  Not recommended. The top lid has a tendency to warp. 

Can I used regular PETG? Yes, but some of the 35 degree angles may have issues. Apply supports if needed. I'll build a profile for this soon.
 

Is there a bolt version coming? Yes! 

Tools for assembly

• Channel lock pliers

• Needle nose pliers

• Flush cutters or utility blade

• Files or drill can be helpful

• Torch (to remove plate residue) 

Printing specs

• 0.6mm HF nozzle preferred for Large Boxes (For the lid & base)

• 0.4mm nozzle can be used for standard size boxes, handles, hinges, & latch (I use ironing for these sometimes)

• 0.2mm nozzle can be used for labels

   

• 0.24mm Layer height for 0.6mm nozzles

• 0.2mm layer height for 0.4mm nozzles

• Gyroid infill

• Box base can be split into two sections in the slicer to allow high infill near hinges. Bottom is 15% 2 Walls. Top is 20% and 3 walls.

Post Processing

Use a torch to lightly remove any plate residue on inside of lid. 

Use flush cutters to remove the brim on the underside of the lid in all six locations:

Check the holes for the pins to see how well they printed. If they need to be drilled out or trimmed/filed slightly then do it - better than cracking a part. 

Pins can be installed using channel lock pliers but I like to get them started with needle nose pliers. Make sure the pin is aligned well as you squeeze it in and take your time. Make sure the flat jaw of the channel locks is against the print - this prevents cracking the prints.

Troubleshooting

If the pin isn't aligned well or the hole has not printed well, it may create a small split in the plastic. PETG HF material & 0.6mm nozzle is accounted for in the tolerances. 

Loose filament along box drawer slides - can be a challenge. Sometimes standard or tree support is the solution here. 

Warping: clean plate! dry material (ideally high flow). Use a brim if necessary. 

Planned Updates

I plan to release other sizes and more accessories as usual. I continue to put a ridiculous amount of time into this project and hopefully that has been reflected in any of the other parts of the system you've tried out so far! Obviously ratings and boosts allow me to get more filament and repair my machines to develop more projects like this. If you want to buy me a coffee, here's a link. The more coffee I drink, the more efficient I am at life, the more iterations and updates these projects get. 

I have a Patreon for support, detailed development updates, and access to early test files. More info here.

Q&A

Why high flow PETG? 

There are some parts on this model that require bridging or stacking at aggressive angles. I haven't seen issues with high flow material. Others have reported issues with slower moving material and machines. If needed, generate support. 

Is this worth all the filament used? 

That's entirely up to you! I find it worth it since it's gridfinity specific, I can print replacement parts, and I know they won't go out of stock or be discontinued. 

Why pins and not printed hardware? 

Many other boxes have printed hardware and some work, some do not. I never found them very durable over time. I use pins often in production products and they offer durability and smooth motion. They are inexpensive and easy to stock! 

Can these be disassembled? 

Drawer frames can be disassembled and reassembled. Boxes cannot - to salvage your pins if something breaks you need to break the hinges to get the pins out. I recommend a flathead screwdriver. I plan to work on a solution for this! 

Where are the bins that go in these?

These are designed for any 6 Unit tall gridfinity stacking bin that follows standards. I do not have any generic bins posted on my profile at the moment but plan to upload some in the near future. I do have many others posted in my profile for bit holders and other items that may be useful for you! 

Can I sell these? 

Yes you can sell the physical prints if you wish as long as you subscribe to the correct commercial membership tier on my MakerWorld profile located here.
