IKEA Relatera LED Desk Lamp (With Dimmer)

This model has the following features:

• Designed specifically to fit into the holes of an IKEA Relatera desk.
• No supports needed on any of the parts (assuming they are printed in the orientation given in the STL files).
• Touch switch and dimmer hidden in the base case with distinct LED dot where to touch.
• Paraboloidal reflector

Printing hints:

• I used white PCTG but any other filament should do.
• I recommend printing the nut and the threaded part of the outer stud with thin layers < 0.2 mm to have a smooth fastening experience.

The additional parts needed are:

• LED strip
  I used rigid MultiBar24 from leds.de, the reflector is designed for those
• LED switch/dimmer
  I used an “Aftertech Dimmer Touch Switch” from Amazon
• 5.5 mm x 2.1 mm DC socket
• adequate DC power adapter (e.g. 12 or 24 volts)
• 4 tiny screws to mount the two parts of the case.
• 3 screws and wing nuts for the hinges
• a wooden strip of an appropriate length for the arm, 5 mm x 10 mm
• some wire to connect the base with the LED strip

Things to consider during assembly:

• The small pins in the reflector are meant to be melted over the LED strip to keep it in place. This avoids having to use double-sided adhesive tape.
• Glue in the small adapter part into the reflector.
• If you do not manage to screw in the DC socket (due to the twisting wires), cut out the inner threads with a drill and glue the socket in.
• Pushing/pulling the DC wires of the socket through the (left) hole can be a bit fiddly. Push in with a pin from the other hole to get the wires bend into the hole.
• Put in the inner stud so that it has to be turned ~180° for the regular lamp position. This way the stud is fixed and cannot be pulled out, only when turned back ~180°.
