Bulldog Lite Extruder, eBay E3D clone heatsink and Heatbed fan mount

thingiverse

Frustrated with my Bulldog Lite extruder I decided to expand on the heatsink fan mount I designed. The Extruder mount comes in two flavours. Either 2 hole mounted, onto the Ooznest carriage, or onto the stock Rework carriage with 4 holes. Included is a STL for a fan mount for an eBay E3D style heatsink. This is practically identical to the heatsink fan mount I've published as a standalone. This one has just been shaved a mm shorter, so the fan is closer to the heatsink. This means if you use a 6mm or 7mm deep 30mm cooling fan, then the entire heatsink cooler will rotate and fit neatly under the extruder mount. Also included is a heatbed fan mount that duplicates spacing of the stock extruder mount, ie the one that comes with it. This means any heatbed cooling solution you are currently using should simply just bolt on without fiddlying around. PLEASE NOTE. The eBay E3D style heatsink clone is different to a proper E3D heatsink. You can look at my photo and just count the number of fins. Whats next?

It does mean that quite possibly a lot of support is needed. But printing this way the layers will be in line with the extruder and I think make it a lot stronger. The shafts in these parts are 3mm and the nut traps fit the 3mm nuts. You will most likely need to tidy up with a 3mm drill bit. Depending of the quality of your print, you might need to heat the nuts to get them to fit into the nut traps. Do not be tempted to rush it by overheating the nuts. The slot the Bulldog lite slides into is meant to be a snug fit. Once again depending on the quality of your print you might just need to give the slot a quick go with a file. eBay_heatsinkrework* Please see my suggestions/ instructions for the standalone heatink_mount I have published. Bulldog_lite_extruder_v7_fan_final Nothing special here. Whatever works. Bulldog_lite_mount_v7_screw_spacing This is not meant to be printed. This is purely if you want to play around with this model. These mean you wont have to pull out a ruler to get your add ons to fit. Post-Printing Acetone fuming. Don't bother on the extruder mount unless you want a nice finish. I tried it on a couple and only thing that happened was the nut traps got buggered up and it looks pretty. Fitting the extruder into the mount is simply to push it in. As said previously you might need to work a file into the slot a bit . It is not meant to be a sloppy fit. The extruder is meant to be held in place in the extruder mount by a couple of m3 bolts. But I wouldn't be surprised if using just a couple of cable ties or even no retainers will work.Use washers but due to the design of the Bulldog the two washers on top will need to have one side filed so it will fit. Fit the bolts from underneath. bulldog_lite_extruder_v7_mount_4_hole_spacing.stl This is meant to be used on the stock rework carriage. Due to the way I decided to tweak this the mounting bolts sit proud of the surface. So the section the extruder slips into has been extended so you can rotate the heatsink fan mount underneath the extruder mount. Heatsink fan mount. If you use a 6mm deep fan it makes no difference what version of the fan mount you use. You can rotate it out of the way under the extruder mount. Suggestions welcome. How I Designed This I spend 7 days and 7 nights meditating beneath a waterfall in the upper Himalayans, till the design came to me in a vision complete and finished. OR I banged my head against the laptop through multiple versions of this design
