Very compact and space-saving under-cabinet reading lamp for LED strips. I have designed the lamp so that the overall height is as low as possible (limited by the switch). The beam angle is chosen so that when mounted just above the head is pleasantly illuminated the book.
I recommend using heat-stable filament such as PETG, ASA or ABS, as PLA loses its shape in the summer months in a warm car. A layer height of 0.2 mm with a filling of 20 % have proven to be very stable. The aperture must of course be printed from transparent material.
Two 3 mm screws are required for mounting. Furthermore, one element of a standard led strip, a simple switch. I have used this from the company Pollin.
