Plywood Air Filter

thingiverse

The user designed and built an air filter for their Thing-o-Matic 3D printer, which initially sat on top of the machine but later was replaced with a plywood version after duct tape deterioration. The filter is made to accommodate a square cabin filter measuring 8"x7.5"x1", commonly found in Toyota and Lexus vehicles like the RX 350, featuring activated carbon for odor control. It experiences some difficulty in installation but the user recommends modifying the top panel for easier access. The air filter is equipped with two 80mm fans on top, which produce more noise than desired; the user plans to reduce their voltage for less noise and more airflow. A simple switch and a RadioShack barrel plug enable control and disconnection of the filter. The design features a short top section that allows LCD controls to hang off the front of the machine while maintaining support at the back. The sides have channels for M3 bolts on the top panel of the 3D printer. The base section measures 3" tall, allowing enough clearance for filament drives without hitting the filter. An LCD and control pad could be integrated into the front panel of the base section for a neat appearance. Measurements are in inches and suitable for 1/4" plywood. Panels are secured with brads and glued 3/4" wood strips for additional support. The user has been using it for weeks, finding it effective, especially for direct filament feed through the top. Assembly instructions are straightforward: cut out, assemble, and enjoy.
