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°.
