Parametric Storage Box

For a project I am working on, I created a parametric box. I thought I might as well share that here as a scalable storage box can be quite useful. 

UPDATE 26 june 2026

Upon multiple requests, I created a box with independent lid and base heights. It is not print-in-place, but very easy to assemble. So if you are looking for something like that, check it out HERE.

UPDATE 27 march 2026

I created a Drill Bit Storage box based on this model. Check it out here: https://makerworld.com/en/models/2577023-drill-bit-storage-box#profileId-2841773

UPDATE 29 jan 2026

• The locking mechanism (latch) has been improved. The original version snapped off too easily and the added lip (oct 25 update) also did not have the desired effect. I increased the thickness as that has been proven to work in another model (with the customizable dividers).
• I've kept the print profile of the previous version (100x60x35) so that you can still print that version. It is clearly marked as OLD VERSION
• The model in the Parametric Model Maker is with the improved latch.

UPDATE 06 oct 2025

• I added a small lip to the locking mechanism so it is easier to open the box. If you don't want this, I added a ‘Toggle switch’ so you can switch it on or off. More instructions below. 

UPDATE 06 oct 2025

• I created a box with customizable compartments in both the bottom and lid. If you are looking for something like that, you can find it here: https://makerworld.com/en/models/1859912-parametric-storage-box-with-customizable-dividers#profileId-1989142

UPDATE 03 oct 2025

• Tolerances of the hinges have been increased based on feedback in the comments. With PLA the tighter tolerances worked fine, but with PETG there were some issues. I don't have PETG filament, so any comments on this would be welcome!
• The locking mechanism has been improved. It is now more rounded and requires less effort to open
• Changed images with pictures of the latest design (grey).
   

The box is a ‘print in place’ design without any assembly needed. Also, no supports are required. The box has a double hinge and has a snap-fit lock. The first time you close it might require a bit of ‘persuasion’ to free the hinges, but after that is works really smoothly. It is almost like a fidget toy: you just want to open and close it ;) 

OUTSIDE DIMENSIONS:

The box can be printed in place with a double hinge between the bottom and lid. Three dimensions can be changed. To do this, click the ‘Customize’ button and the Parametric Model Maker will open:

1. Box width: the width of the box. Minimal width of the box is 92 mm, otherwise the hinges won't fit. Maximum width is limited by your printer.
2. Box depth: the depth of both lid and bottom. Minimal depth is 25 mm, otherwise corners won't work (and the internal space is too small). Maximum depth is limited by your printer.
3. Box height: this is the TOTAL height, so bottom and lid combined. The minimal height is 35 mm, otherwise the lock won't fit. 
   Example: a box height of 40mm results in a lid and bottom height of 20mm each. Maximum height is limited by your printer.

All dimensions are maxed at 400 mm (more than most printers can have…).

LOCKING MECHANISM

A small recess in the bottom halve of the box catches a latch on the lid. The thickness of the latch had been increased in the January 2026 update to prevent it from snapping off too easily. The first 3 images (cover image not included) are of a box with this strengthened latch. The other images are of boxes before this update.

INSIDE DIMENSIONS:

Due to wall thickness, the inside dimensions are smaller:

1. Box height: total height - 8mm; the lid and bottom have the same internal height: (Total height/2) - 4 mm
   Example: a total height of 40 results in a total internal height of 32 mm. The lid and bottom internal height is 16 mm (40/2 -4); 
2. Box width: total width - 10 mm
   Example: a total width of 100 mm results in an internal width of 90 mm
3. Box depth: total depth - 9 mm
   Example: a total depth of 80 mm results in an internal depth of 71 mm.

The bottom half has a small extruded lip (2 mm) that slots in to the lid.

If you want to create your own custom inlays, the rear corners (near the hinges) have a radius of 3 mm and the front corners (near the lock) have a 4 mm radius.

In the images attached, there are some sample sizes (H x W x D)  of

• 35 x 120 x 50 mm (grey example)
• 25 x 92 x 30 mm (last image)
• 35 x 120 x 60 mm (last image)
• 40 x 172 x 90 mm (last image)
