Stimulating Slugs in a pouch

thingiverse

I recently bought a corpse grinder cult to play necromunda, but some of the accessories in the rulebook don't have models, one being the stimm slug. I've been told that the goliath gang has some, but I'm not buying a new kit for just one accessory so I modelled an approximation of what I think a pouch of stimm slugs should look like.
