UV nail dryers handle

thingiverse

From x2 cheap 365um nail dryers, into a powerful 405um UV curing box with digital timer! Handle is little bigger than my print area (210mm vs 200mm), so I split it into two parts. Also, it helps to attach it properly with the screws to the dryers, and then combine both dryers together. First handle print failed, so I print missed part and glue them together to save the time. I used rivets to attach handle to the box, as I was to lazy to use screws and nuts there. In other case - **attach handle half to each dryer and then do final assemble of the box**. Default 365um UV lamps were replaced with 405um UV leds, which are much more bright and powerful and with exact wavelength for resin curing. If you plan to order such UV leds, check, that they are **exactly 405um and not with double length 365+405um** (such led-lamps have double leds and no way to disable one mode). From what I know, 405um give better curing, and resin don't get yellowish tint. Digital timer was bought from local store for like $10. Only pay attention, that you need a electric socket **timer with the COUNTER mode** (at least that how this named in mine) - usually similar timers allow only to put exact time to turn it ON or OFF, and that is not an option, as you will had to do this, to adjust time, on each timer run. And the "counter" mode allow to set the timer for selected period of time, form a few minutes to several hours, and it starts on single button press.
