Fraks Flexarm – Heat-Set Insert Press

The Fraks Flexarm is a tool-balancing arm designed to keep the attached tool parallel throughout its movement. It was created to hold soldering irons to install heat set inserts into 3D printed parts.It has a large working area for its size, and has quick release tool holders that are held in place with magnets.Thanks to Zack Freedman for making Gridfinity an open source project, I have included Gridfinity storage into the base. You can read more about Gridfinity at https://gridfinity.xyz/ What do I need? You will also need either pocket screws or a wood working fence clamp to secure the base to your work surface. 4 pieces of 1515 extrusion, all cut to the same length and tapped on either end. I have tested this with 200mm and 270mm lengths. 10x1x60mm extension springs, these seem to work well for 200-300mm builds. You can adjust the tension rate by moving the spring posts along the 1515 extrusion. 10x100mm dowel pin and a 10x14x30mm brass Bushing M10 washer, a 25mm diameter is listed,
