MakerFarm 10" i3v build

I'm very excited to see your print cooler thread posts printbus!

Totally agree! I am hours away from installing one controlled by D9 and anchored via the hexagon cooling fan screws, but maybe I'll wait for your design!?!

There will be those who don't like the print cooler I have. I'll try to get it added to the build thread sooner rather than later.

MiniMad - it'd be interesting to see a rear-mounted cooler. That might have pretty wide acceptance since it wouldn't be in the way of anything. I started with that concept. It just started getting real bulky by the time the fan or blower was located far enough back to clear the v-rail and carriage wheel, and then a shroud had to sneak below the carriage and get around the wheel at the bottom of the carriage. I sketched a concept up on paper, but concluded it was way beyond my current design capability.

I even toyed with the idea of a blower mounted on the outer sidewall of the frame, above where the MeanWell type power supply usually goes. Some sort of flexible hose could then curve down to the bottom of the carriage where I envisioned a shroud was attached. The local ACE Hardware had some 3/4-inch ID corrugated discharge hose that might adapt well to the square or rectangular hole in a blower. If it hadn't been overpriced at $4 USD a foot, I'd have tried that.

I was also intrigued by http://www.thingiverse.com/thing:271875. It uses the split cable loom as an air tube from a blower mounted on the unused extruder motor bolt hole for a Robo 3D printer. The tubing and copper wire length might have to be different for an i3v, but it could work for many depending on how the hot end wiring is routed.

Clough's print cooler was strapped onto the left side of the X-carriage on my printer for a while as well. I put it there after I had an extruder base melt-down with the print cooler mounted on top of the low-flow fan I had installed for the stock hex cooling approach.

The more ideas out there the better.

Tracking still isnt showing when my printer is due
Can someone please tell me what size glass I need to get so I can go ahead and have that cut?
Looks like most are getting a peice thats full width, and then having it a bit shorter depth to clear the bolts?
That seems easier than attempting to break the corners off.

Well I ended up going with a side mount cooling fan. I just couldn't figure out a good solution from the rear or front. My goal was to use an existing 40mm fan and whatever hardware I have sitting around. There are some issues to the mount I have, namely the angle is a bit too broad and I want to add a keyway to keep the mount in place, but using the existing mounting holes on the x carriage, it seems it will do a good enough job without any mods to the printer itself

Nice and simple solution.

Am I missing something, or would this be a good solution?

Opps, nevermind, says it doesnt work with the stock setup.
Only works with this setup, which also seems nice.

I'm using the stock hot end (reprinted after it melted once... See http://3dprintboard.com/showthread.p...ll=1#post25399 and printbus's follow up with an easy fix). I wonder if the lower two screws on the cooling fan could be used to mount a smaller version of https://www.thingiverse.com/thing:351280 for a 25 mm fan.

makerfarm_print_cooler_R.stlWell life interrupted my progress this week and I haven't had time to revisit the model I drew up the other night. Will hopefully get around to it tonight or tomorrow. So much to print, so little time!

Edit, here's a quick revamp of the model I posted before. The tab on the right edge is designed to 'hook' around the outside front edge of the x carriage, which should provide the support needed to keep the mount from moving. The screw hole is simply aligned with the single screw on the side of the carriage. Will print it this weekend and see if it fits!

Here is my print cooler design: http://www.thingiverse.com/thing:462768

This parametric model styled after clough42's allows you to try different fan sizes and alternate mount points by controlling the angle and diameter of the nozzle away from the fan. I have one setup that seems to work with a 25mm and another with 40mm.

To help in getting the print cooler positioned absolutely perfectly so it will not interfere but still offers maximum airflow over just the top of the hot end, I ended up coming up with these items:

http://www.thingiverse.com/thing:463758

They are pretty generic and can be used to mount a lot of the different print coolers (see the list in Thing Info section).
