I tried something new with parametric design. 😄 Today I publish the first batch of heart decorated boxes for 3D-print in 500 different sizes.

The sizes start from 35mm up to 120mm in small steps, so you can choose a box in the perfect size for you.

The print above is a very small one, with inner dimensions 40×35×20mm. I printed it on a Prusa i3 MK3s, with a 0.4mm nozzle and the PLA Prusament “Viva la Bronze”.

Part Numbering

To choose the right box, you need to know the inner dimensions. There are width (x), depth (y) and height (z) to choose. If you want to print a box with the dimensions 35×70×60mm, search for a file named like this:

LR2103H-x035-y070-z060-box.stl

For the matching lid, search a file like this:

LR2103H-x035-y070-lid.stl

Because the x and y dimensions are interchangeable, there is no file LR2103H-x070-y035-..., for these dimensions, always put the lower value in x.

There are two different type of lids for each box size. The regular lid, with the suffix -lid has a spacing of 0.1mm, which should work with all 3d printers. If this lid feels too lose for you, there is a lid with the suffix -lid-tight which has spacing of 0.05mm.

You find the STL files for all boxes in the following GIT repository:

How to Print the Box

It is a very simple print and should work on most printers. For best results:

• The box is made for FFF. I recommend using a Prusa printer..
• Use PLA for the box. I recommend using Prusament filament..
• Use a 0.4mm nozzle, but 0.6mm and 0.8mm should work fine.
• Use 0.1mm or 0.2mm layer height for the print. The object is optimised for these layer heights.
• Do not scale the model!

Conclusion

This was an interesting experiment and it turned out very well. I plan to publish more of these boxes with different ornaments and shapes.
