3D printed electronics enclosure (FDM)
Our own hand-sized case for a battery-powered sensor board, designed around its parts and FDM printed in our Singapore studio.
- What it holds
- A microcontroller, a sensor board and a battery
- How it opens
- The lid lifts off and stays wired to the board
- Battery check
- The battery level shows through a window in the lid
What we brought
Designed around the parts
Every part has its own place
We laid the case out around its microcontroller, sensor board and battery holder, with the battery across the base.
Easy to open
The electronics are a lift away
The lid lifts straight off and folds aside on its wires, so the board is in reach for testing.
Finished in print
The lid carries its own markings
The large 5 is printed into the lid, and its textured face hides fingerprints from everyday handling.

The brief
Step 1 of 4
- Inside
- Microcontroller, sensor board and battery holder
- Lid
- A window for the battery-level indicator
- Access
- A lid that lifts off by hand
At Additive Inn, our 3D printing studio in Singapore, we designed a hand-sized case for a battery-powered sensor board as our own project. It had to hold every part securely, open easily and show the battery level without opening.
Production
Step 2 of 4
We FDM printed the base in green and the lid in black in our studio. The lid carries a large numeral 5 and a window for the battery indicator, with a fixing hole in each corner.
Build and assembly
Step 3 of 4
We fitted the microcontroller and sensor board on a carrier at one end of the base and the battery holder across the other. The battery indicator sits in the lid window, wired to the board.
The final build
Step 4 of 4
The finished case closes over its electronics and opens in a second for testing, with the battery level always in view on the lid.
