Extruder spring tension hat

My all-metal extruder for my Ender 3 came without the little steel hat for the spring tension screw so I made this little guy. The hat is 10mm x 7mm. It has a 10mm x 1.5mm brim/base, the inner shaft hole is 3mm W x 3.5 mm D and the outer shaft is 7mm H x 5.5mm W to fit inside the spring. This leaves a strong 3.5mm thick top layer to handle the pressure of the spring on the screw and the 1.5mm brim is strong enough to handle the pressure without breaking or warping. The full height leaves enough room between the top of the hat and the other screw for the tension screw to be fully seated if required (if you need the tension screw fully seated to get proper tension, you may have other issues like a weak spring).

• 0.12mm layer height for extra strength
• 100% infill for ultimate strength
• No supports needed
