I got various requests and great ideas from you about how to improve the storage boxes system. Thank you very much for all the great ideas and suggestions! ๐
One request I got many times was storage boxes with a flat bottom. The reason for this was to have a straight surface to store objects and tools in the box. I could solve this problems in three ways:
- Create a new box series without a groove at the bottom.
Pros: Minimal change in print time and material use and you gain additional volume.
Cons: These boxes were not compatible with the existing ones and are limited how you can stack them. - Add material to the bottom to make it straight.
Pros: Boxes are compatible with the existing system.
Cons: The print time increases and you lose volume in the box. - Create an insert for the boxes.
Pros: Existing boxes can be used, therefore compatible with the existing system. The insert can be replaced at a later time, keeping the box.
Cons: You lose some volume in each box. You need to design your own insert.
I went with the last solution and thought how to provide the best implementation for you.
The Insert Template LR2052-801
I prepared a parametric Fusion 360 design you can download for free.

This template generates inserts for the flat box series. It contains the parametric design for a simple raw spacer block. Use it as a start for your own insert.
There are three parameters for you to use or change:
- count_x
The size of the box in units in the X-direction. If you have a box 1×2, this parameter should be 2. - count_y
The size of the box in units in the Y-direction. If you have a box 1×2, this parameter should be 1. - inset_fill_height
Do not change this parameter. This is the recommended lowest distance between the bottom of the insert to your removals. You can use this parameter in your sketch. - inset_working_height
This parameter controls how much material is added to the fill height. Use a minimum of 2mm, otherwise, the insert is not connected or will break easily.
The Drill Insert Example LR2052-802
To demonstrate the template, I also added a drill insert example design. This parametric design will generate inserts for various drill sizes.
Just open the sketch “example – edit this!” and adjust the parameters “drill_count” and “drill_diameter”. The sketch will be updated with the new parameters. If you adjust the “drill_count”, you also have to edit the last cut operation with the additional profiles.
STL Files
I added STL files for the raw insert block generated by the template to the package. You can use them with other tools to modify them to your needs.
OpenSCAD Scripts
I also added two OpenSCAD script you can use to create inserts and even customised drill inserts.
Download
You can download the insert set on the page with the free downloads.
Conclusion
I hope this insert templates will help you print perfectly tool inserts for your boxes. If you organised your tools using my storage box system, please let me know and publish some pictures.
