Note: I've realized that the E27 support was not ideal and week, so I designed a new one stronger. Lamp_Modular_E27_Holder v2.

I liked this version to add a grow lamp to my plant. Unfortunately the socket I had for the led light was of E27 type. But with a bit of tinkercad, I was able to remove a piece of the lamp support and add a hole for my own :)

To make the lamp in the photo I printed:

2xArm_150_w__channel.stl 1xArm_90_w__channel.stl 1xArm_Axis_Changer_v5.stl 1xLamp_Modular_E27_Holder v2.stl

Then I used M5x20mm screws.

Note: as said on the initial drawing I remixed from, the arms print a bit funny on the cable run, but I don't need it anyway so all good.
