Highly recommend cleaning your plate prior to printing, consider using glue stick to promote bed adhesion. There is low surface area keeping it in place during printing. 

I picked up a small air plant recently and needed a holder for it. I couldn't find anything I liked, so I ended up making this! It sits 50mm tall at its current scale and the narrowest part of the opening is about 20mm wide. It is designed for a small plant but could easily be scaled up to accommodate larger plants. I hope you enjoy!
