Meant for SLA 3D printer, never tried it on FDM. To fill the pendant I use some generic two component clear epoxy, I put some black pigment to the epoxy to glue the rose to the base and cover the base structure of the rose. The epoxy I got is old so I had some issue with bubbles in the last one I made, you can notice them in the video, but still looks cool.
