Hot End J-Head Bowden Filament Guide

thingiverse

I had some cheap Chinese J-Head Bowden Hot-Ends collecting dust around me. The problem always was getting the filament in, due to a gap between the heatsink and Bowden tube connector. So I designed this little spacer (I call it spacer). It fits perfectly between the heatsink and Bowden connector, allowing the filament to slide easily inside the hot-end. It works exceptionally well. Please try out how it fits - there are two versions available: one with a 2.2mm hole and another with a 2mm hole. You might need to rescale it. Print Settings: Printer: Kossel XL Rafts: Doesn't Matter Supports: Yes Resolution: 0.05 Infill: 10% Notes: Print in the finest layer height you can achieve. Depending on which side you print, you might need support or not. Because this is a small part, print slowly and with cooling enabled. Post-Printing: After print Maybe you'll need to sand it a bit. Try out if it fits - if not, rescale the part. I made two different versions for this reason: one with a 2.0mm hole for filament and another with a 2.2mm hole. You could also drill the hole yourself.
