For $40 you can build this awesome heat press/ I have tried several and this is by far the best one yet. I removed one spring from each joint and oiled and adjusted the joints for smooth operation.  The opening is 19mm for the soldering iron. It is based off DIY engineering's video on you tube but designed it for this soldering iron.
