WWBMG RIDGA smooth idler arm

I grew impatient after I received my RIDGA set but the pack of idlers were not delivered yet so I found some bearings from the drawer, measured it and started remodeling the idler arm to fit the bearing so I can already start testing the new extruder (https://github.com/Armchair-Heavy-Industries/A4T/tree/main/3mf/WW-BMG%20for%20A4T).

About 100 hours in I can highly recommend it if you don't want to pay extra for the idler gear. Works with all filaments and if your hotend is up to snuff, it will print beatifully.


YT Short of it trying to push more ABS filament in than X1C hotend can melt at 250C. As you can see, there's plenty of grip it even flexes the toolhead printed out of Spectrum ASA-X CF10 mounted to Chaoticlabs CNC TAP v2.

Uses a bearing of 11mm outer diameter, 5mm inner diameter and 5mm width, also an M3 washer. I would give the model but the bearing has nothing etched on it. Use 10..16mm long M3 flathead or smooth head bolt. Do not overtighten it as it is driven straight into plastic, but longer bolt will have better grip anyways. 

Rendered using aluminum look so if you are a chad, then you could actually machine it out from aluminum. Added the .step file also that has just the arm.
