Bench Heat-Set Insert Press
A fully printed bench press that holds any soldering iron barrel 12–22 mm dead vertical so M3/M4 brass heat-set inserts go into printed enclosures square instead of crooked — no arbor press, rods or donor hardware. The 90° vee carriage rides a print-in-place dovetail column (0.45 mm clearance) and is strapped to the iron with a rubber band or zip tie in the 7 mm retaining groove; the 80 x 73 mm base has two insert trays and four M4 clearance holes to bolt it down. Overall 80 x 73 x 105 mm.
