Railcore II Cooling Fan Modifications and Add-ons

Railcore II: Cooling Fan Modifications and Add-ons

Update 5/15/2020 - making major revision, pulled files until I can update thanks

I made a few mods/add-ons for the Railcore II cooling fan(s). As of now the most popular/effective fan is the James Tongue Mandible and that's what I've focused on, though more may come as other fan options become available.

These mods are part of the Emma Puggle Railcore II collection and are compatible with the Printed and Aluminum Y-Carriage mods ONLY. Those mounts move the hot end from it's standard position to maintain a straight filament path from the Bondtech BMG through the hot end.

Tongue Mandible Adapter [ALU]

Remix/rebuild of the adapter included with the James Tongue Mandible to be compatible with the Emma Puggle y-carriages. Couple notable changes from the original mount:

• Uses brass inserts rather than a captive nut solution

*Requires M3x3mm Brass Knurled Threaded Insert https://www.amazon.com/gp/product/B01IYWTCWW

• Includes a multitude of spacers to put the fan output precisely where it's needed (1mm above the print bed suggested)
• Variant includes a bump stop for anyone running a Sensorless Homing configuration (Aluminum Y-Carriage only at this point)

Tongue Mandible Adapter [PRINTED]

• Adapter for printed y-carriage

*Requires M3x3mm Brass Knurled Threaded Insert https://www.amazon.com/gp/product/B01IYWTCWW

Tongue Mandible Fan Support

There's a chance for the weight of the fan to cause the mount to droop. This simple bracket supports the weight of the fan+duct by attaching it to the belt retainer.NOTE: currently only compatible with the Emma Puggle Aluminum Y-Carriage Belt Retainer as it adds a mounting point for the bracket.

Y-Endstop Mount for v6 Groovemount Piezo

When using the Piezo Mount for the E3D v6 Groovemount Heat Sink, the piezo mount interferes with the y-endstop mount. This replacement, courtesy of John O'Shaughnessy, pushes out the endstop just slightly to clear the mount.
