My youtube channel where i assemble and test my lures : https://www.youtube.com/channel/UCdslaelZqMrTIzADEtbC7eA

This is a work in progress but i'll share it anyway.
It's still a work in progress because i do not like the action without the lip.
The line tie and hook attachments are twist wire (check any assembly video on my youtube to see twist wires being made)
Just glue those in, paint and glue on some eyes.

As for the wall thickness; experiment. i go with 2mm but it depends on the sink rate you want. 2 mm walls and two, 1 gram splitshots will make it sink slowly.
Print with the rear on the bed and use small raft so it doesn't come off during printing.
