Holder Ring for Litho Luminaries

this little ring is the right size to fit under a solar lamp used in these lithos... then you can string up or wire up a hanging one... i included the original scad file if you want to edit it a bit, but it is pretty simple... can easily be glued to underside, but doesnt have to be.. it wont fall thru... so you could change it every once in a while, etc...
