My pandan tumbled three times during the last time due to its weak trunk. Every time it was destroying its flower pot. So I designed a support to further hold it in balance. The corners are designed for a "greenmotion plant pot 40cm x 40cm". Print two bows, eight tube ends and four corners.
Edit 2021/04/09: Printable bolt and circlip added to save metallic bolts and nuts. Print 8 bolts and 8 circlips.
