I often had the need to take a closer look at a print, a nozzle or the tip of a filament. 
To have enough light for an inspection I decided to place a flashlight at every printer I own.
A cheap but powerful flashlight is the SK68 which can be easily found on Ebay, Amazon and Aliexpress. 
One problem remained: where should I to put it?

So I designed this simple mount that can be placed on almost any surface.
It can be attached to an aluminum-extrusion, a wooden shelf or a wall by using screws or a double-sided adhesive tape. 

The need to attach it to a metal-door or a computer-case made me make a second design using 8x3mm magnets (use some glue).

The print can be done in PLA or PETG without any supports. I think ASA or ABS should not be a problem, but I didn't try it.
