A super easy and fast tree to print if you just use these settings Single wall print Thickness: 0.8mm Nozzle: 0.4mm Fill: 0% Temperature: 220 Speed: 30mm/s Bottom/Top Thickness: 0mm Use Spiral function if available Here is the trick to get a nice clean top of the tree. Tweak settings for the last 10mm of your print by using the tweak at z pugin in CURA (oh how I love CURA!!) Speed 50% of original speed (15mm/s) Lower the temp with 10 degrees to 210 decrease the flow by 10% to 90% of original flow If you don't alter these settings, most of the time the top of the tree will droop down/inside. Enjoy your print and merry Christmas!!
