Springless Capo_classical with M3

thingiverse

The "Screwless Guitar Capo" underwent modifications, now functioning perfectly with our classical guitar. The upper part was extended 7mm to reach all strings while the curved string side was straightened. The clamp portion was adjusted shorter than its original size. This capo is compatible with M3 screws and nuts. I printed it using PLA material with a 3-layer top and bottom, at least 3 perimeters. A M3, 30mm locking screw provides the ideal length. To enhance the design, I added a countersunk M3 surface for the screw and drilled a small pit for its end. The main axle hole on the top part is enlarged using a 3mm drill, while the other hole is secured in place without nuts. On the top part, I applied double-sided soft tape followed by porous material (thin rubber works well), and heat shrink was used on the clamp portion for protection.
