What we brought

  1. What we can do

    We turn your sketch into a cutting file

    Their DXF sketch became a dimensioned flat pattern in stainless steel 304, every cut-out placed for the rolled sleeve.

  2. How we look after you

    You mark it up, we redraw it

    Their team marked up our drawing the same day; we kept their figures and redrew it in three days.

  3. What you get

    A sleeve that opens and locks by hand

    Four hinges and four toggle latches let the sleeve swing open and clamp shut without tools.

Stainless steel 304 sheet
Latches
Toggle latches on curved plates, to sit on the round sleeve
Carrying
Loops for a strap

At Additive Inn, our 3D printing studio in Singapore, we drew a stainless steel carry sleeve for 18 DA Bn, Singapore Armed Forces, and had it made. It wraps an RBS 70 missile, and their team sent a sketch to start from.

Design and prototyping

Step 2 of 5

We turned the sketch into a dimensioned flat pattern in two pieces, each cut with the windows and slots the sleeve needs once rolled. The unit marked up our drawing, and we redrew it to their figures for Revision 0.

Production

Step 3 of 5

The two stainless steel pieces were laser cut from the agreed profiles and rolled into the sections of the sleeve. Stainless steel 304 was left raw: it resists rust outdoors and needs no paint.

Build and assembly

Step 4 of 5

Four hinges were welded on and four toggle latches fitted, the latches on curved plates that sit flat on the round sleeve. It swings open on its hinges and clamps shut by hand, with no tools.
