Beam Compass

thingiverse

This precision beam compass is engineered to accommodate pencils of all sizes, ranging from slender graphite sticks to full-size Sharpies. A sturdy pencil holder is carefully press-fit onto a robust 1/2" dowel, with an optional small screw available for added security if needed. To bring this innovative design to life, you'll need the following essential components: A single 1/2" wood dowel Two high-quality 5mm x 35 length or longer hex bolts Two durable 5mm wingnuts Two reliable 5mm nuts Two versatile 5mm thumbscrews One premium 1" or longer bugle / gold screw Inspired by two decades of experience with poorly crafted beam compasses from hardware stores, which often cracked or failed to securely hold pencils and pens in place, this design sets a new standard for precision and reliability.
