3.5 mm LED lantern and support.

For a Deeper Understanding of the Printing Process. Print Settings Printer: Prusa Mendel Hibryd Rafts: No Supports: No Resolution: 0.1 or 0.15 mm layers Infill: 0% or at will. Notes: 0.25mm nozzle, PLA, 200° C, Fan cooling. Post-Printing Clean up the thread pitches with a metallic nail file. Soldering is unnecessary if you use cables with an inside diameter that matches the LED pins, allowing the cable's plastic cover to serve as electric insulation. Connect the LEDs in series when using 12 V and choosing not to employ circuit boards or resistors. How I Designed This I aimed to illuminate the printing area, so I split the 12 v from the cooling fan's energy cable with four 3.5mm LEDs connected in series; diverting the energy from the fan due to the low energy consumption of the LEDs. I decided on a retro-style shape reminiscent of old cars or bikes. The spherical support joint allows for various settings, yet remains strong enough to withstand printing head movements. Following the introduction of light into the printing area, my comprehension of the printing process and print quality significantly improved. Noticing bed mis-calibrations during the first layer deposition becomes straightforward when illuminating the printing area. Custom Section Observing the printing process is highly beneficial and entertaining for me, primarily because I prefer creating designs that don't require supports. Some printing mishaps can lead to unexpected thicknesses and angles; there might be a way to utilize these "accidents" to achieve more intended results.
