I have created this simple design to utilize a very cheap LED light for a plant growth support.

The strip is 8 mm wide and 50 cm long, using USB power supply (powerbank, phone charger, laptop etc.).

Due to that design's modular nature, you can adjust a holder length by combining 50 or 100 mm long parts and connectors using M3 nuts.

I have also included parts without holes - you can easily glue them without using nuts.

You can also import stls and modify them (parts without holes are easier to import and to manage).

This is the first version of that design, it's not pretty but very useful :)

My print settings (PLA):

• Printer: Anycubic i3 Mega S
• Bed: 60 C
• Hotend: 210 (first layer), then 205 C
• Nozzle size: 0.6 mm
• Layer height: 0.28 mm
• Layer width: 0.64 mm and 0.48 mm (both work fine)
• Supports: no
• Brim: no
• Print speed: 60 mm/s

Designed using Fusion360 with almost zero skills :)
