Christmas Tree w/ lights

thingiverse

The tree models require additional support. To print the tree without lights, print the file labeled tree-cutout.stl, and it's not necessary to print base.stl or tree-flat-bottom.stl. A small star component needs to be attached to the top. Printing the tree with lights involves printing the files tree-flat-bottom.stl and base.stl, and omitting tree-cutout.stl from the print list. It is advisable to print the tree with zero percent infill for best results. When trying to print bottom layers or upper sections, it was found that Cura needs to be utilized to ensure attachment of these parts. Removing support materials required the use of a razor blade and precise cutting skills, resulting in accessibility to internal structures within the tree model. Inspectants observed grey/blue plastic material on the inside which resulted from applying JB plastic weld to mend separated layers following disassembly of support materials. For the purposes of installing lights, I employed two LEDs in series with a 100 ohm resistor connected to five sets in parallel attached via a USB cable. This power setup pulled approximately 30 milliamperes during usage, keeping well within usb-powered device safety limits. Light transmission into the star portion was accomplished by heating up a three-sixteenths inch drill bit using a lighter, which allowed a small LED light source to be installed within. The same process may utilize other heat-tolerant materials including hot glue, welders, or JB goop to transmit the led light signal while preventing obstructions on its path through the top tier and star segment. With the installation of lights within the tree structure complete and the upper section well lit up by them, it becomes feasible for the model tree simply sit upright on the given base stand. This is achieved without applying adhesives or fastening materials due to secure integration thanks to carefully implemented application techniques using additional support pieces applied to provide necessary structural reinforcement throughout construction and disassembly stages combined to achieve robust cohesion as seen upon close examination in hand, especially after the lights installation process that required use of multiple light sources with corresponding heat dissipation features within respective electrical setups implemented according to established best practices among users seeking optimal performance at reasonable operating temperatures for these particular assemblies constructed from three-dimensional modeling output files prepared by using software tool designated '3D modeling and computer-aided manufacturing software application name - possibly in future revised to better fit intended market appeal target demographic, e.g. '3d print modeling studio' and subsequently used by users aiming towards practical real-world uses cases that demand attention towards usability within context.'
