Gridfinity Storage Box by Pred (now parametric)

IMPORTANT

Read the description carefully before print!

Check the changelog at the bottom before printing, there might be updates to the model

The original model and the parametric one are not stackable with each other! 

Prusa Mini version: https://www.printables.com/model/556604-gridfinity-storage-box-by-pred-for-prusamini

Now PARAMETRIC

Find the f3d file in the common folder below.

I did some changes compared to the original model.

• It is now parametric with bunch of options
• The base lost some weight and now can accept 6x2 magnets (if that is your thing)
• It got a front handle (optional) *
• Redesigned label holder
• Option for a hinge with an M3x30 screw

* I don't like the handle, but that was a commonly requested feature. It for sure change or might even be removed in the next iteration. Also it steals a lot of space from the label, so it got smaller.

What can you change?

Dimensions

Of course the dimensions (number of bins in X and Y and height in Gridfinity units)

• X is limited to minimum 4 bins (the label and handle are barely usable in this size)
• Y is limited to minimum 3 bins
• Z is limited to minimum 6 units

Lower values will break the model!

Hinge size

You can now change how long the hinge is and also the Y position from the back of the box and the size of the axel. The wider the hinge axel the stronger it is, but also gets harder and harder to print without support.

The options are limited for the screw hinge!

Label size

Within reason :) For smaller boxes, this does not add much, but for bigger ones there is some room for customization.

Description (original model)

Let me introduce you the newest and shiniest iteration of Gridfinity storage box.

A 5x4 Gridfinity baseplate hidden in a 230 x 188 x 55mm box (Z+1.5mm stacking tab on top), secured by a grid of Gridfinity container bottom profiles in the lid, complete with a label holder.

The boxes are stackable and also can be secured to eachother by the catches.

To use it as a standalone box, you'll need 2 catches (on the front), to fully stack and secure multiple boxes together, I recommend 6 catches in total, but optionally can be used with only 4 (however just for the looks, I prefer to have 6).

All parts are fully printed, no need to use any bolts and nuts.

Inspired by the Gridfinity Project Case and Rugged Box (Parametric) and several other commercially available boxes, like Makita's MakPac and Festool Systainer.

Print instructions

I printed all parts in (Prusament) PETG using a 0.4mm nozzle and 2 walls and strongly recommend PETG.

You can increase the wall thickness if you want, in exchange of more material usage and slightly longer print time. The Base, lid and the hinge can benefit from the more thicker walls.

Base

• Recommended profile: 0.3mm DRAFT
• I recommend adding supports to the bottom of the locking tabs and the label catch*. (~2m filament) ( * only in the original model)
• Place it right side up

Lid

• Recommended profile: 0.3mm DRAFT
• I recommend adding supports next to the hinge slot for the long bridging
• Change the bridging angle to 45 degrees (Print Settings → Infill → Advanced → Bridging Angle)
• Place it right side up

Hinge (printed)

• Recommended profile: 0.2mm QUALITY
• 3 walls, 100% infill
• Should print fine without supports but if it fuses completely, add supports to the bottom of the cylinders.
• Place it standing on the bed

Hinge (screw)

• You can print it the same way the printed version (bolt head part facing down), or print the two parts separately and use appropriate support for cleaner result.
• You'll need an M3x30 bolt and an M3 nut per hinge.

Latch

• Recommended profile: 0.2mm QUALITY
• Supports might be needed on the bottom of the tabs on the side
• Place it flat face down

Label

• Recommended profile: 0.2mm QUALITY
• Place it flat face down
• You can add text or other modifiers in the slicer or edit the model in your choice of mesh massager
• Keep a 2-3mm border untouched on the face around the perimeter

Handle (optional)

• Recommended profile: 0.2mm QUALITY
• Parametric only
• Print flat
• No supports needed (the filet might be ugly on one side, but that does not affect functionality if printed on a reasonably calibrated printer)
• You'll need 2 pieces of M3x14-16 bolts, no nut, screws into the plastic or the handle pin if printed parts are fine for you

Handle pin

• Recommended profile: 0.2mm QUALITY
• Can be a bit hard to insert, but should click in place and hold the handle securely (you might need a tool to push it in)

Bins inside

• Those are stackable 6U high Gridfinity bins, use recommended settings of your choice of bins
• See the Gridfinity section below
• My design of the bins: https://www.printables.com/model/592545-gridfinity-bin-with-printable-label-by-pred-parame

Assembly

1. Slide in the catches into the rails on the sides and the front of the base
2. Insert the 2 hinges into the holes on the back of the base
3. Carefully align the free ends of the hinges and secure the lid
4. Insert the label into the slot
5. Close the catches on the front
6. Optionally use 2 pieces of M3x14-16 bolts or the printed pins to secure the handle. The bolts screw into the plastic.

The tolerances are a bit tight for the catches, you might need to file off a bit of material from the tabs on the sides of the catches if they prove to be too hard to close. They should close without noticeably deforming the base or the lid while properly securing the lid and/or the box on top.

Gridfinity

Zach Freedman laid the bases of this organization system and shared as is an open source project. To print the containers inside (or similar ones), search for “Gridfinity bins” or similar on almost any model sharing site.

In order to lock the bins with the lid in place (and prevent the items in the bins spilling out), fill the full height in each place you use. The lid accommodates for the stacking lip, which adds 4.4mm to the bin's height on top of the 42mm.
