Mini USB nightlight socket for HH's Soy Fish Lamp

A low wattage light really accentuates HH's Soy Fish Lamp design for me as the reduced brightness allows all of the lamp shade details to be seen. This also has the advantage of greatly reducing the heat produced in the lamp.

I've redesigned the internals of the cap to be almost exactly the same (a little taller) but to fit a male to female USB cable as the 'socket' for using the 1W or similar 5v USB nightlights that are easy to find on Amazon or Ali Express etc.

The exact USB cable I designed this around is a Pro Signal cable (PSG91458) which you can find on Element 14 or CPC, but the USB holder is a slight tapered fit and would likely fit other cables too e.g. these ones from USB Gear (let me know if you try!).

Dimensions of the USB cable female end rubber casing I used are:

• 17.15mm wide

• 9.75mm thick

• 27.75mm high

Everything else is exactly the same and fits the same fish lampshade and screw as the original.

Print instructions

Follow the print and assembly instructions for the Lampshade and Screw from HH's Soy Fish Lamp, leaving the cap and all it's parts.

Print the modified USB holder Cap and cable clip using: 

• 0.16mm layer height (to ensure sure the threads function nicely)

• 3 walls

• 15% Gyroid infill density

Assembly

Thread the male end of the USB cable through the USB socket holder all the way and then insert the female end until it's snug inside the lamp base.

Then put the cable through the cable holder and insert the cable clip into the slot to hold it in place.

If you're up for it, as an optional extra you can then wire a switch into the USB cable for inline switching, see this post for detailed instructions on the proper wiring. Most inline switches are the screw terminal block kind and don't require soldering but this details the proper wiring e.g. only cut and connect the red 'power' wire to the switch leaving the 3 other USB cable wires intact and routing them around to the side.

Requires

• The Soy Fish lampshade and Screw from HH's Soy Fish Lamp

• 1 x Male to female USB cable

• 1 x USB nightlight or other similar sized USB powered LED (~1W recommended)

• 1 x Inline cord switch (optional)
