Christmas Tree (now with lamp base)

thingiverse

Oh Christmas Tree! Oh Christmas Tree! Designed to be printed in a single wall vase mode, photos show it printed in transparent green PETG. A fairly large model measures 210mm in diameter and stands at 300mm tall. Scale the design to fit your printer as needed, and consider scaling the z height separately for a more slender or robust tree. Remember that this is a non-commercial license; print these trees only for personal use or as gifts for friends and family. If you plan to sell them, contact me for a commercial license. A study of various materials can be found on YouTube: https://www.youtube.com/watch?v=qexqRiBG268 I've added a new faceted version with lots more bling, featuring the last two trees in the video above. Screenshots are included to show where to find vase/spiralize mode in three popular slicers, resulting in faster prints. UPDATE 12/21/2016: I've also added two files for E27 light bulb holders: "Short base" for regular LED light bulbs (be sure to check the warning) and "Tall base" for specialty bulbs like the disco RGB LED bulb that creates a nice Northern Lights effect. A lamp base is now available for the 300mm tree. However, be cautious when using E27 light bulbs, as they may get warm enough to soften the holder (triple-check this before use). Print Settings: Printer: Tronxy X3 Rafts: No Supports: No Resolution: 0.2mm Infill: 0% vase mode Notes: I printed without base layers so that a light can be placed inside later. Four brim loops at 0 distance were used to ensure the first layer stuck well. A bit of over-extrusion helps the layers adhere, and running hotter with slower speeds will help achieve optimal results. Printing time varies depending on filament, but it took approximately 4 hours and 42 minutes to print at 0.2mm and 100% (300mm tall). However, by increasing speed, I was able to get prints completed in around 3 hours and 45 minutes. For E27 light attachments (short base and long base), print with three perimeters/shells at 0.2mm layers. Post-Printing: I found clamp work lights make a nice base when disabled and reassembled without the clamp, and those I found at big-box stores are UL certified. The trunk base was designed for E27 light sockets with switches purchased from Aliexpress. While of questionable quality, these switches should be sufficient for low-wattage LED bulbs; however, use them at your own risk. Do not rely on them for anything over 10W, and make sure they do not get warm. How I Designed This: I stay in shape by using Onshape.
