What we brought
What we can do
It opens to take the coil
The enclosure splits in two and opens on a hinge, and snap-fit covers close it over the coil.
How we look after you
The connectors decide the split
By the third revision the casing splits between the two BNC connector holes, so each half has one connector hole.
What you get
Checked on a real part
We printed the holder in our studio and fitted the coil inside, to check the split, the hinge and the covers in the hand.

- What it holds
- A metal coil
- Connectors
- Two BNC
- Our scope
- 3D design for manufacture over three revisions, and a test print
At Additive Inn, our 3D printing studio in Singapore, we designed a holder for a metal coil for SP PowerAssets. It is a clamshell enclosure that opens on a hinge, closes with snap-fit covers and has two holes for BNC connectors.
Three revisions
Step 2 of 5
We took the holder through three revisions. Each one came as renders with its changes called out.
-
Revision 0
A hinged enclosure with a snap-fit cover, a compliant mechanism to take up 1 mm of tolerance, and two BNC connector holes, one above the other.
Render
-
Revision 1
The two BNC holes side by side, the cover split in line with the enclosure, and a snap-fit lock where the halves meet.
Render
-
Revision 2
The casing splits between the two BNC connectors, so each half has one connector hole.
Render
A test print
Step 3 of 5
We printed a test holder in black in our studio: the two halves of the enclosure and the two cover halves.
The coil goes in
Step 4 of 5
The coil sits in the enclosure around its centre tube, and the cover halves snap on over it.
The final build
Step 5 of 5
SP PowerAssets received the 3D files of the holder. Our test print closes with both covers on, as in the design.
