🚀 Extruder Spring Compressor (2mm & 3mm)
Are you noticing random under-extrusion, slipping filament, or strange imperfection patterns on your outer walls? Before you drop money on an expensive dual-gear upgrade, your stock extruder spring might just be losing its grip.

Over time, stock springs on the Ender 3 and other Creality machines can weaken, leading to insufficient tension on the extruder gear. This Extruder Spring Compressor is a dead-simple, print-in-place shim that slips right into your extruder assembly. By instantly restoring the perfect amount of extra tension, it stops filament slippage dead in its tracks—resulting in a consistent flow and drastically improved print quality.

🌟 What's New? (Updated Today!)
Smoother, More Effective Design (V1.1): This latest update features fully optimized, rounded tolerances. It now slides flawlessly into modern stock Creality plastic extruders and upgraded aluminum single-gear extruders without needing to force it or shave down the edges.
Enhanced Rigidity: Redesigned from scratch in Tinkercad to be structurally stronger than older community concepts, ensuring it won't crush or deform under constant spring pressure.

📦 Choosing Your Size
Finding a replacement spring with exact dimensions is a massive headache. Instead, just choose the thickness you need to tune your tension perfectly:

2mm Shim (Extruder_Spring_Compressor2mm1.1.stl): Perfect for a slight, subtle tension boost if your gear is only slipping occasionally.
3mm Shim (Extruder_Spring_Compressor3mm1.1.stl): The sweet spot for most older or heavily used printers experiencing regular under-extrusion.
Pro-Tip: Since these are incredibly small and print in just a few minutes, print a couple of each! If 3mm still isn't quite enough, you can even stack a 2mm and a 3mm together to dial in a custom 5mm compression.

🖨️ Recommended Print Settings
Material: Standard PLA works completely fine for this print!
Infill: 50% to 100% (Solid). Because this part lives under constant mechanical compression, high infill is essential to keep it from flattening out over time.
Supports: None needed. Drop it on your plate and print!
