Universal Mounting Module for Bambu Lab Rechargeable Power Kit  ZC003

While working on a new motorized project using the Bambu Lab Rechargeable Power Kit, I realized it was a perfect candidate for something I increasingly do in my designs: creating reusable modules.

Instead of designing another enclosure just for that project, I decided to invest a little more time and create a universal mounting module that I could reuse in future projects—and eventually share with the community. As I gain more experience with CAD design, I also find myself thinking differently about new projects. Whenever I create a part that I expect to use again, I try to turn it into a reusable module in Fusion 360.

Many iterations

This project went through far more iterations than the final model might suggest. 

I experimented with several internal layouts, including versions where the electronics board was mounted vertically to reduce the overall size. Although those designs looked promising, they never felt quite right.

The USB-C connector and power switch had to align perfectly with the housing, while the electronics also needed to remain easy to remove. Since the whole idea is to reuse the module in future projects, permanently trapping the electronics inside the enclosure was never an option. I tried many different locating tabs, support ribs and retention features before settling on the final solution. In the end, placing the electronics board flat on the bottom and securing it with the cover plate proved to be both the simplest and the most reliable design.

I don't mind investing extra time in a reusable module because I know I'll benefit from it in future projects. Most prototypes solved one problem while introducing another. Each iteration brought me a little closer to a solution that was compact, practical and easy to reuse. Only after many small refinements did everything come together in a design that felt right. 

I hope this reusable module helps other makers spend less time designing electronics enclosures and more time creating the projects they actually want to build.

I'm looking forward to seeing what the community creates with it.
