thingiverse

If you're looking for a high-performance, highly customizable Bowden extruder design, this one's worth checking out. What does the RSE-2 have to offer? The design is easy to reproduce on even simple printers. The number of required parts is surprisingly small and all the necessary parts are easily obtainable. The design can be easily customized to meet your own needs with various options available. No fiddling around with filament feeding, this extruder offers real "speedloading" - just push in the filament lightly and let the extruder do the rest (without any prep work!). Check it out: https://youtu.be/vTWcHaKl36A. Due to its very small stretches without defined filament guides in the extruder, flexible filament can be processed more easily. (Depending on your printer's setup) Here is an overview of the non-printed parts needed: 4 M3x30 cylinder head screws 2 M3 nuts 2 M3 support plates 1 spring / pressure spring (Tip: a spring from a liquid hand soap dispenser fits perfectly) 1 push fit with a 5mm thread for connecting the Bowden tube with a 4mm outer diameter 1 piece of Bowden with a 3mm outer diameter approximately 11mm long (optional) 1 hobbed pulley (MK8 style) with an 8mm outer diameter, 5mm inner diameter, and 13mm height 1 Nema 17 stepper motor For further questions: rse-2@tinyfactory.de (You can also order the extruder as a parts set or as a complete unit here) Have fun with the design!
