KNOB - PRONG INSERT - M4 [SET 2 of 7]

🔧 Purpose This knob is intended for applications where you: • Need a robust, easy-to-replace thread • Want to print spare knobs without sourcing special inserts • Prefer a standard hardware solution instead of proprietary parts • Use widely available prong T-nuts (pronged tee nuts) instead of heated brass inserts – no special tools required The design can be adapted to many projects, including fixtures, jigs, tools, or machine handles. 🖨️ Printing Tips • Material: PETG recommended for higher durability (PLA also possible) • Layer Height: 0.2 mm • Infill: 30–50% • Supports: – Required for the caps (due to overhangs) – Main knob body does not require support if printed upright • Perimeters: 3–4 recommended 🛠️ Assembly Instructions Insert the prong nut: • Heat the nut slightly if you prefer a softer press-fit. • Alternatively, lightly hammer it into place if your print tolerances are tight. Attach the cap: • Align the cap with the knob body. • Press-fit or glue in place for permanent mounting. • The cap can also remain removable if preferred. Mounting: • Install the knob on your threaded rod or bolt. • The prong nut provides a secure, reliable thread for repeated use. Note: You can also flip the knob and print it flat (without the lower lip) if you prefer an alternative assembly approach. 📏 More Sizes / Variants More knobs in this series are available in my profile: • M3 • M4 • M6 • M8 • M10 • M12 All models are published separately to allow convenient downloads for each thread size.
