AirArm - Articulated Scroll Saw Air Blower

thingiverse

A friend was fed up with his Ryobi scroll saw's static air blower, finding it an obstruction to smooth use. He'd observed that newer scroll saws featured flexible air blower arms and wondered if it could be retrofitted into his own. This DIY fix addresses this need.\nIt utilizes ball and socket joints designed by Giuseppe Finizia for the PCB Workstation with Articulated Arms, complemented by a base plate and end effector to securely hold a standard aquarium tubing. The base plate and end effector were built using OpenSCAD and can be customized for various uses (base size, air line diameter). Both components draw upon the "BS_Joint.stl" file from Giuseppe's PCB Workstation, ensuring that modifying these components won't compromise compatibility with pre-printed joints.\nFor modification of SCAD files, users might find it more practical to retrieve the source from the project's GitHub repository.\n\n \n \n Assembly Guide\nEdit and customize the SCAD files for the base and end according to needs, then print these along with necessary lengths of "BS_Joint.stl". Next, attach the base plate firmly to a stationary part of the saw (3M double sided tape used effectively) and feed the air line into the end effector. In cases where the tool lacks a built-in air system, users can make use of standard aquarium pumps.\nTo prevent excessive movement while operating the saw, ball and socket joints can be secured with additional tape or shrink tubing to maintain stability.
