(100 mm)

All parts print without supports if laid on the correct face in slicer.

There are three variants of the LED holder:

1. single 5 mm LED (straw hat LED works great)
2. single rectangular 1W LED
3. three 5 mm LEDs (again, straw hat LEDs look very nice)

Also necessary are:

• M3 heat set inserts: 2 for the lid, 2 to 4 for the battery compartment
• I used M3 countersunk torx head screws: 2 pcs. M3x6 for the lid, 2 to 4 M3x10 to mount the LED holder to the battery compartment
• TP4056 battery charger module, I used the variant with battery protection circuit
• a rocker switch, I use https://www.amazon.de/gp/product/B07QB22J62/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1
• a Li-Ion battery pack of your choice
• obviously, LEDs of some sort, I like these straw hat ones: https://www.amazon.de/gp/product/B01BUVHSSE/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
• I use a constant current source for my LEDs to get constant brightness over varying battery voltage
