I added a ring to scanlime's banana-slug model to make a pendant that can be used on a key chain.
In the pictures with 2 slugs, the gold slug is scanlime's original design, printed in Hatchbox Gold PLA on someone else's 3D printer. The green is the modified design.
In the 3-slug picture, the filaments are Monoprice green PLA, Hatchbox gold PLA, and CC3D Silk gold PLA. The silk gold is particularly shiny and jewelry-like.
Looks good in either Hatchbox Gold (for a subtle gloss) or CC3D Silk Gold, for a shiny jewelry look.
I used OpenSCAD's import function to get the banana-slug design, then added a ring (a torus flattened on the bottom).
