Hot glue stick
thingiverse
PLA melts at about the same tempurature as low melt hot glue. I am going to try printing this and running it through a hot glue gun to attach prints. Size is 11mm x 110mm. You can scale it for longer if you have a taller printer. Smaller one is 7mm x 110mm. I am printing at 95% infill to avoid overprinting.
