Filament Straightener 2 axis

thingiverse

This is just another filament straightener, a straight filament creates less friction in the bowden tube. It also enables you to make use of those last turns of filament that are tightly coiled around the center of the spool. To assemble it, you'll need a 3.3mm drill and a M4 threading tool. The drill is used to clean the holes before threading. When I thread the parts, I soak them in water to give lubrication and cooling, don't thread too fast or it might cause the plastic to melt and destroy the threads. On deep threads, retract the tool when you're halfway down to remove waste before continuing with the last part. I bought the parts on eBay; I won't update the links when they become obsolete, but it's not hard to find similar items: Washer M4 4x9x0.8mm (14pcs) http://www.ebay.com/itm/M3-M4-M5-M6-M8-M10-Stainless-Steel-Metric-Flat-Washers-Screw-Repair-Kit-Tool-HPT-/191543215195?var=&hash=item2c98dd845b:m:mrW8YYdorSzqVhz08qLUDFQ V-Groove ball bearing 4x13x6mm (ID,OD,Thk) (10pcs) http://www.ebay.com/itm/10Pcs-Metal-Sealed-Guide-Wire-Line-Track-Deep-V-Groove-Pulley-Rail-Ball-Bearing-/321898243903?hash=item4af2a1673f:g:jJQAAOSwT5tWJeYd Socket head cap screw M4x18mm (8pcs) http://www.ebay.com/itm/M4-304-Stainless-Steel-Allen-Hex-Head-Socket-Cap-Screw-Bolt-DIN912-/182015074419?var=&hash=item2a60f1a073:m:mGVj6hugxesvZHLkvNoie3Q Countersunk head screw M4x20mm (10pcs) http://www.ebay.com/itm/M4-304-Stainless-steel-Countersunk-head-Allen-Hex-Socket-Screws-Bolt-DIN-7991-/172090959814?var=&hash=item28116ba7c6:m:mrQV7wodUyXWZNQQHbLQf4A M4 nut (6pcs) http://www.ebay.com/itm/M3-M4-M5-M6-M8-M10-M12-M14-M18-M20-M24-DIN934-316-A4-Stainless-Steel-Hex-Nuts-/322100947156?var=&hash=item4afeb668d4:m:mnrFRS45COubg8NUndMvimg Thread tap M4x0.7 http://www.ebay.com/itm/Hot-M3-M4-M5-M6-M8-High-Speed-Steel-HSS-Screw-Thread-Metric-Spiral-Hand-Plug-Tap-/201482756375?var=&hash=item2ee94ee117:m:m3UsDejuY2Syig2jSvTJpyQ Update V2: Added two more v-groove ball bearings to guide the filament in and out of the straightener.
