I made an E27 lamp as a gift. It is printed in multiple parts that you can assemble without any screws.

Additional parts required: A mini Wi‑Fi or Zigbee Tuya smart switch (for example: link - try to get a module size 404020) – used as a button, and it lets you connect your lamp without any soldering or programming with Wemos, ESP or other ways…. An E27 cable An E27 bulb (a mini bulb looks nicer)

Print settings: I print all parts at 0.16 mm layer height with 15% infill, but the larger parts can also be printed at 0.20 mm.

Start by inserting the cable into the base of the flower top. Thread all wires through the stem (don't forget the interior support tube) and into the base enclosure. In the base, insert the button into its hole (assemble the two button parts together). Place the switch under the button and connect the 4 wires. Fit the enclosure over it and secure the bottom of the lamp.
