I created this lamp for my workspace right to the printer.  With 6 10x5mm neodymium magnets, it attaches perfectly to the printer (I believe 4 strong magnets is more than enough). 

The lamps used is a pair of T5 30cm Led Lamp like this: https://es.aliexpress.com/item/1005006782634990.html more than enough. 

This is the second model I've made for the lamp: the first one had the weight further from the base, which made it more prone to falling (besides, it turned out much uglier, so I didn't plublish it :| ). This design seeks to place the weight at the level of the printer's profile and to create a shade to avoid dazzling anyone who passes by the printer. Both objectives are achieved, and the lighting is fabulous.
