Folger Tech (Knock-Off) E3D V6 - Bowden to DIRECT Conversion Kit

thingiverse

The text describes a DIY modification to an E3D hot end, specifically for use with flexible filaments. The goal is to create a smooth and gap-free path for the filament through the hot end. Here are the steps: 1. Trim the ends of the idler and drill a U-shaped section in it to allow the PTFE tube to seat properly. 2. Bevel the edge of the remaining PTFE tube to match the gear and bearing curves. 3. Insert 1-2" of trimmed PTFE into the top of the extruder base, which serves as the filament inlet. 4. Secure the idler with a spring and M4 bolt and retaining nut, adjusting the tension until it grips the filament tightly but doesn't flatten it. The modification aims to eliminate kink-spots or bind points for the filament, ensuring a smooth path through the hot end. Print settings: * Printer brand: RepRap * Printer model: Folger Tech Prusa i3 Aluminum * Rafts and supports: No * Resolution: .12mm layers, 0.4MM nozzle * Infill: 100% * Notes: The idler must be printed at 100% to prevent the bearing from breaking. Post-printing: * Use a 5/32 drill bit to clean out holes for the PTFE tube. * Use an Exacto to remove excess plastic from the outside of the insert, taking care not to get it stuck in the hot end. The design relies on precise printing and assembly to ensure smooth operation. The author notes that they haven't fully tested this with flexible filaments but believes it should work without issues.
