ERC Pen Attachment

thingiverse

This Pen Attachment is designed specifically for use with the ERC TimSav CNC needle cutter, leveraging a standard clicker pen that's widely available. I employ this attachment for calibration purposes as well as for drawing precise designs onto poster board for my flight test planes. To secure the pen in place, I utilized two 3mm screw inserts and took advantage of the stock hole locations on the cutter to ensure accurate positioning. The slots are cleverly designed to allow effortless raising or lowering of the pen for both use and storage.
