USB/Battery Powered Soldering Iron - Upgraded Case Inlet - TK-USB-DS

The original crappy plastic case annoyed me - so i designed a new one. Remove the cheap plastic inlet and use this one :) The soldering iron can be purchased here: https://s.click.aliexpress.com/e/_c3nbfaHn https://s.click.aliexpress.com/e/_c38g8EcV https://s.click.aliexpress.com/e/_c41QZaA1 https://s.click.aliexpress.com/e/_c4eytorL https://s.click.aliexpress.com/e/_c3z0HmjL Get proper tin solder from a local store Print Note: Print the spool element twice and glue it together Print the flap standing upwards using support and rim, see picture Print with 0,20 or better to get good results Note: There is no space for the flux/resin in this design (don't need it, the provided one is trash) The tin solder provided is also trash, do not use it
