Minimalist wall lamp

A minimalist wall lamp: one fourth of a sphere, that's it.

Designed to be printed as large as possible on an AnkerMake M5 (235×235 mm); finished size is 270×135×135 mm.

I used the experimental fuzzy skin feature on PrusaSlicer, and it makes for a great effect – with different settings – both on the shade part and on the base.

Clearly, don't use anything else than LED light bulbs: we are printing in plastic!

Other materials needed

• a G9 light bulb socket
• a G9 LED light bulb
• a connector to the power line: I used (and designed a slot for in the model) a KF128 connector, but it can easily be adapted to most other small connectors
• hardware to hang it on the wall: 2 screws which should have ⌀3.50-3.75 mm and have a head of ⌀5.0-7.8 mm and < 2mm thick. Note that a drilling mask is also provided with the STL files.

Print Specs

Shade

• Clear PETG
• Layer height: 0.28 mm
• Infill: 100%
• Fuzzy Skin, if desired: use the provided Shade_fuzzy_mask STL file to mask only the shade surface, and not its supports. Settings: 
  • Fuzzy Skin: Outside walls
  • Thickness: 0.3 mm
  • Point distance: 0.8 mm
• No brim, no skirt, no supports: they are already built in the model

Do expect a bit of warping with this kind of thin shape, but especially if you print it with the fuzzy skin it is really barely noticeable.

I assume that it could also be printed with clear or white PLA, for a different effect. Do beware of the lower temperature that PLA can withstand with respect to PETG.

Base

• Black matte PLA+
• Layer height: 0.16 mm
• Infill: 15%
• Fuzzy Skin, if desired: use the provided Base_fuzzy_mask STL file to mask only the external surface, and set:
  • Fuzzy Skin: Outside walls
  • Thickness: 0.1 mm
  • Point distance: 0.1 mm

G9 socket adapter

Since not all G9 sockets are the same shape, I thought it better to design an adapter for the one that I got. Its shape is quite a common one, and this adapter should fit many.

If you have a different one, redesigning just the adapter is pretty easy, compared to modifying the shape of the base itself.

Just for reference, this is the socket I used, and it is the one this adapter is designed for:

It is a pretty easy and cheap one to find in Europe on Amazon and, no doubt, in other countries as well.

When printed on a printer with tuned tolerances, this socket adapter should press-fit into the base and lock the socket in place.

If you remake this socket adapter for other types of sockets and want to send me the STL file, I will gladly add it to the files.

Cable lid

Not mandatory, but it makes for a nicer finished look. Print it with the same filament and params as the base.

Putting it together

It is really super simple, but here are some pictures, just in case:

Simplified print

If you just want a quick'n'dirty print and don't care about fuzzy skins and other details, you only need to print the files:

• Base
• Socket_adapter
• Shade_with_support
