Printing in other colors or with transparent PLA may allow light through; do so at your own risk. You won’t need to use a raft, brim, or supports provided you have a properly calibrated and sticky build plate.\u003c\/p\u003e\n\u003cp\u003eDesigned for quart sized mason jars, these sleeves block light from all sides except for a narrow viewing window. For better visibility inside the jar, I recommend slipping a piece of white paper inside the sleeve. A helpful cutout located halfway up the viewing window indicates the maximum fill level. Do not refill your Kratky jars above this tab or you risk drowning your plant’s roots.\u003c\/p\u003e\n\u003cp\u003ePrinting recommedations:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cmeta charset=\"utf-8\"\u003e \u003cspan\u003eBlack or other fully opaque dark color recommended; material doesn't matter so much but I use PLA\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eInside brim recommended if your build plate has adhesion issues\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSupports not required\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan\u003e--\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eIf you like my work and want to support me, please \u003ca href=\"https:\/\/stephaniecervi.design\/shop\/\"\u003echeck out my online store\u003c\/a\u003e, \u003ca href=\"https:\/\/www.patreon.com\/stephaniecervidesign\"\u003ebecome a patron\u003c\/a\u003e, or \u003ca href=\"https:\/\/ko-fi.com\/stephaniecervidesign\"\u003ebuy me a coffee\u003c\/a\u003e.
