Thanks.

I printed one and installed a JHead. I haven't mounted it to the X rods yet. It looks to attach to the rods as in the previous versions. It appears the fan mount provision is to the mount points for the groove mount bracket. The hole spacing is the same as on a 40 mm axial fan (IIRC 32 mm) and with a spacer. The bottom of the fan contacts the heat block if not offset from the mount. I think something like a hinged fan mount might work. I may be able to whip something up this week. I modeled a mount that attaches to the groove mount clamp that will mount the fan shroud from an i3 Rework. The model says it fits. I'll print one off in the next day or so and post some pics and source if it works.

thank you for your feedback,

I will certainly make the attach larger , so the fan won't touch the heating block anymore.. it's not suposed to happend

Thanks for your feedback. Whats the purpose of that pin on the right? Where the microswitch gets mounted? Also it needs support for bowden mount. I think its still an work in progress. The fan should be slightly angled to blow also on the print.

All Repraps are a work in progress.

Here is a mount for a Rework fan shroud. The shroud is in the Rework Github, the source for the mount attached to this post.






There are both an Inventor ipt file and an stl attached. Looking at it it would make more sense to add a mounting point for the fan to the clamp in the dist rather than the bolt on part I have here.

Edit: The limit switch mounts to the two holes perpendicular to the top of the mount. The spacing is for the original Makerbot style switch on a board, it would need a mod to use a plain microswitch.

The Bowden fillting can be tapped into the top of the hot end. Or in the case of an E3D there is a push in fitting.

Same with both the Genie hotends, they come with Bowden fittings and can be removed for other types of systems.

MK2 has a E3D mount and that can also be used on the MK1 hotend.
Bowden fitting not shown, but it just screws into the top of either hotend and is supplied as standard.
