Bedside night light
An amber, 1800 K bedside light that stays under the melatonin-suppression threshold, so a 3 a.m. walk to the bathroom does not cost you the rest of your night.
Configure
Order today and it arrives around 24 September.
It contains a lithium cell. Shipped assembled, the cell travels as UN3481 (contained in equipment); loose in a kit it becomes UN3480, which is not carried by express air at this volume.
Or €69 in 38 days on the batch lane.

Buildable as specified
- Dome onto body needs a secondary operation
H9/d9 at Ø90 mm asks for a tolerance the as-moulded process does not hold. Snap-free push fit that survives 500 open/close cycles for the battery; tighter and the dome scuffs.
→ Specify reaming or facing after the primary operation, and state it on the drawing.
- Built in PA12 + 30% glass fibre, not ABS
SLS 3D printing cannot run ABS. On this lane the part is PA12 + 30% glass fibre: 1.35 g/cm³ against 1.05, and 110 MPa against 42. The surface is different too — printed parts have a fine matte grain that a moulded part does not.
→ Order on the batch lane to get ABS as specified.
- Speed is most of what you are paying for
Air freight is €13.87 of a €35.56 landed cost — 39% of it. This part is heavy enough that flying it costs more than making it.
→ The same configuration by sea takes about 38 working days and cuts the freight to roughly a fiftieth.
- The moulded version carries draft the printed one does not
Body prints without draft on the express lane, but injection molding needs 1° on every face parallel to the pull. Over a 90 mm wall that moves the surface by about 1.6 mm.
→ If the two must be interchangeable, design with draft from the start and accept it on the printed part too.
- Ships assembled — not a choice we make
It contains a lithium cell. Shipped assembled, the cell travels as UN3481 (contained in equipment); loose in a kit it becomes UN3480, which is not carried by express air at this volume.

What is fixed, and what is yours
The parameters above move; the components do not. Every unit uses the same released bill of materials, from the same certified suppliers, because changing the electronics means repeating the certification — expensive, slow, and invisible to you. The freedom is in the geometry, which is the part you actually see and touch.
body and diffuser dome are made for your order by sls 3d printing. That split is the whole reason this can arrive in 8 working days instead of six weeks.
