Fan mount for 40mm fan, Prusa v1 x carriage. This fan cools the workpiece.

(while the solid model files are not a WIP, the text for this "thing" is. Further documentation will be added as I remember it :)

This replacement x-carriage should help anyone out who prints with pla. I didn't find one that I liked so I put this together to direct a nice cool flow of air to the upper portion of the hot-end. It takes a common 40 mm cpu/gpu fan and is a really clean method to attach a fan. I'm designing another one that includes a second duct to cool the E-motor.

I hope it is useful for everyone needing better cooliing for the hotend.

I've uploaded the final V4 STL called "xcarriagev4done_fixed.stl". It has been passed through Netfabb and is only 2.6 megs compared to 12.3 megs for V3. It prints nicely without requiring any support. The fan mount clears the diagonals nicely and the bushings fit well, too.

After some problems extruding ABS through my J Head MkIV nozzle I decided to install a fan for active cooling whilst printing.

As I needed an offset mount for anything smaller than 50mm for my X-carriage, I designed this mounting and guard.

Simple and minamalistic!

I recently built the Ninja CNC kit from CNCSNAP.com. They recommend you use a fan to cool the board but they don't include a fan or an enclosure. So it bought a "thunderblade" 80mm blue led fan from radio shack and designed this enclosure for the board. I didn't feel like designing fastener attachments for the top-base connections so I just heat welded them together.
Feel free to modify the design to use a different fan if you like.

Very small parts print better with a little bit of cooling to stop them overheating and melting. I designed a simple bracket to fix the spare fan from my Huxley kit onto the existing bolt on the X-axis idler.

I really did not like how the extra cooling fans mounted on the Mosaic. The big thing that I hated was that the secondary cooling fan blocked the view of the build! I like to watch! This is a simple design that moves the fan to the side of the extuder.

I really did not like how the extra cooling fan mounted on the Mosaic. The big thing that I hated was that it blocked the view of the build! I like to watch! So here is a design that mounts the secondary fan on the side, and it has a nozzle that moves the air near the extruder.

It may be a bit of overkill just because I am still learning up the tool chain, and I may refractor the nozzle/fan air chamber as one part at a later time.

I will also post just a side mount fan mount without the nozzle on another post(http://www.thingiverse.com/thing:13881). It is far simpler if you are just looking to move the fan out of the way.

I had to modify the original Fan Duct, mirroring on Y axe, because we didn't place the head in the same header hole.

There are quite a few fan ducts on thingiverse, but I didn't find any for a Gen7/Sanguinololu style row of pololu drivers. So here's mine. It is sized for a 60mm fan. I'm working on an 80 mm version in case I need more oomph. (I naively bought 2A steppers before realizing that the pololu's won't do anywhere near that without serious cooling.)

The aerodynamics of this duct are very poor. I'll try a more curvy version when I get around to it.

There are two parts to this, a plate to mount the Gen6 board on the Prusa top bars, and a fan mount that allows you to mount the fan above that. The fan mount can be used separately.

For the fan the mounting holes are fixed, but the fan aperture hole, thickness and pad height are parameterised so could be adjusted for a different fan size.

There is a third file to print the board to mount and mount to fan spacers. These are optional if you have an alternative. Again these are parameterised to alter height, hole sizes etc.

In the gen6 mount scad file there is an optional line that you can uncomment. This will add a block with a hole though it that can be used as a filament guide.

This mount goes on the left side of your Prusa on what ever excess threaded rod you have hanging oout. This is a great spot because you can point it at your controller, Y motor, X motor, or your print bed. If you don't have one yet and you like it, I got mine at Best Buy but I'm sure you can find it just about anywhere else.

(First upload to Thingiverse!)

I wanted to use a 25mm fan with the recently published Gen6 electronics cover by Logzy thingiverse.com/thing:12302.
My ducting is delicate with it's single filament wall thickness, but holds the smaller (25mm) fan just fine. (Sketchup drawing below if you want to modify.) The ducting clips into the slot in the cover, and the fan just sits into the square on top. A dab of hotmelt glue secures the fan.

Had an 80 an 80mm fan in the junk box, so I thought I'd mount to my Prusa for cooling when printing.

I am currently the proud owner of a newborn Reprap Prusa Printer.

I still have some way to go in getting my RepRap performing at it's peak. What I have learned so far is that cooling your printer is important. As well as keeping the thermal barrier cool in the hot end of the printer, the other area of the printer that gets nice and toasty is the electronics.

I tried to passively cool my StepStick stepper motor drivers with some heatsinks, but after a long session printing they were pretty hot. So I designed this.

The Ramps Cooler/Guard is a pretty simple design as you can see, but it is effective and pretty neat.

I also felt that it would be useful to me to gain a little feedback from my printer so I have added three holes to the right hand side of the piece to furnish two red LEDs and a green LED. These quite simply are connected to the power input, heat-bed heater and extruder tip outputs on the RAMPS board. The green LED tells me that there is 12v power to the the printer, the red LEDs come on when my heaters are active.

The mounting holes for a RAMPS shield match of course the Arduino Mega, so there may be other applications for this design. In a future version I may add a power switch, but feel free to add one if you use my design.

IMPORTANT. The mounting holes will need adjusting in the .scad file for your printer/hardware.

This is a forced cooling enclosure i created to suit the Gen 6 electronics.
The fan duct is glued onto the main cover as im too lazy to change it to a snap on, plus glued could have several advantages.

The cover snaps onto the base and a 40mm fan is attached to the fan duct.
This creates a wider higher pressure flow of air for cooling in the important places.

It provides good forced cooling keeping the board cool.

This thing is a mount to put cooling fans on both sides of your MK7 extruder in a single extruder setup. This setup is for a non traditional mounting setup, it probably will not work on your thingamatic without work.

It is designed to cool both the plastic being printed and the part itself using 2 30mm fans.

It is designed to use 2 self threading screws from above to attach to the MK7 mounting plate.

I have included all of the Autodesk 2012 files including the assembly file. If any other file types are wanted request them I may be able to post them.

The part assumes you have 1 inch between the bottom of the nozzle to the bottom of the mounting plate.

I will print as soon as I get a replacement stepper driver in the mail.

And for those of you opening it in inventor I have no idea how it became a sheet metal part, but it makes no difference when generating the stl.

A table stand for a standard 92.5mm computer fan, meant to use some of the leftover threaded rod, smooth rod and other hardware from making a Prusa Mendel. I created it so that my "helping hands" can be relieved for duty and do other things than cool my prints.

This is a thing in progress. Please go ahead and print it out and let me know how it's coming along. This is my first "thing" and also the fist thing I've ever designed in 3D or with OpenSCAD.

It seems that everyone uses 50mm fans, it just so happens that i have a dozen or so 35mm fans laying about. Smaller the better in my mind. No need to over do it.

There are many mounts included in other parts, and i wanted to use my smaller fans in those locations.

I'm currently using an arcol.hu hot end which i like very much. I think the design is great. It has a thermal break (PEEK) and even a simple heatsink on the cool end. even so, i've had some heat related failures about an hour or so into some big prints. Even with the heatsink, heat starts to creep up, though the hotend itself and also through the extruded material. having an extruder jam an hour into a big print is one of the most frustrating of failures, am i right?

I needed to mount one of my fans and i could have blue-taped it and been effective, but why not keep it clean? This mount uses two of the mount holes for a 50mm fan and positions and directs the fan where i need it.

I uploaded two versions, one offset, for my particular use, and a centered version which would work fine in most cases.

now the heatsink stays ice-cold (room temp really, poetic license, sue me) and i haven't had a heat related failure since.

This is a fan holder for a 50mm x 50mm x 11mm fan.

It was inspired by this thing: thingiverse.com/thing:8183

I made it because I could not find the right current setting for my stepper driver to keep the motors cool, and not lose steps.

I've added a butchered heatsink to improve the cooling capacity.
Now my X stepper stays cool, and doesn't mis a step!

As an added bonus, there's a hole for the wires.

The Y heatsink doesn't need a fan because it's bigger.
It's held in place by a suitably edited large paperclip.

I really wanted one of Iwo's ducted cooling fan ( thingiverse.com/thing:5756 ), but only had a 40mm fan, so I printed his thing, then made an adapter ring to fit my junk box 40mm fan.

First version of my optional clamp on nozzle cooling thing for printing small parts. This version is more effective if your fan is not so strong. It only aims a fan to the nozzle.

Around the nozzle cooling for 5x5cm fan for building small prints!

This is a derivative of my own prior extruder barrel cooling duct. ( thingiverse.com/thing:8461 )

It is optimized for a 40mm fan, which won't fit inside the 35mm gap between the two large sides of a standard MK5-6 extruder. I find that PLA prints much better with active cooling directly on the barrel itself.

The section STL is for a replacement side to the extruder. It is functionally identical to the original small acrylic piece that fits there - except that it has a big rectangular hole to allow additional ventilation.

I've of course included the OpenSCAD design files, but I didn't try to make the fan mount terribly parametric. There are some variables you could set, like thickness to all parts, but it's not fully parametric. If you have a different fan from mine (40x40x26mm) then you're going to want to redesign the fan mount anyhow.

The reason for the DXF of the front acrylic panel was so that I could essentially create a virtual extruder holder for making sure everything aligned. If you uncomment the section at the top, you can see it too. ;)

I like the DC Fan holder.
Transporting my Thing-O-Matic often I choose a very wide and long fan instead,
so it would never break of. (40x50 instead of 40x40 and 32mm thick with 2 fans and 2 motors)
Mine also uses a very strange bolt-size of M3.5 .
This required a redesign.
I am using 2 flat pieces on either end of the fan
instead of housing this large thing inside the DC fan holder.
My clamp-arm is not parallel to the wood but starting at 4mm and ending at 5.
This way it will clamp more securely and with more force.

To still attach it easily I tapered the arm by 2mm
(and the bolt holes by my usual 1mm).

The arm is also not as long as the fan.
With the fan 10mm wider, the arm would get in the way of the Z-endstop.
Thus it ends 15mm short of the back wall.

With some ASUS products a radial fan is included.
I made an adapter for this fan so i can use it for other cooling purposes.
The sketchupfile is attached.

i had some small 12v fans laying around that i thought would work perfect for cooling down my Z stepper.

so i came up with this part to mount it.

*the fan is roughly 35mm X35mm X 10mm

short video recap:
youtube.com/watch?v=kMfU4rV7ook

I was charmed by the design 'Ducted cooling fan by Iwo' so i designed one for the Ultimaker
It's lightweighted, tiny and it gets the job done.

The duct and the roof are seperated for better cooling performance (no hanging roof makes less airflow resistance)

This is a bracket that positions a 40mm diameter cooling fan over the Pololu A4983 stepper drivers in the RAMPS (RepRap Arduino Mega Pololu Shield).

The fan used was a 40X40X20 12VDC FAN, RS Stock No. 544-0526 uk.rs-online.com/web/search/searchBrowseAction.html?method=searchProducts&searchTerm=544-0526&x=25&y=8

The fan is countersunk into the bracket and fixed in place by M3x30 socket screws.

Additional holes in the corners of the bracket line up with the mounting holes in the shield board. M3 stud, coated in PTFE tube (d3D4.5) to prevent any shorts, was used to position the bracket above the shield.

The fan can plug into the 12VIN and GND-IN pins just beneath D8 on the shield.

This is a simple mounting system for a fan. It was designed for a MakerBot Thing-O-Matic. I am pretty sure it will work for a cupcake. I needed some simple solution while I wait for my MK6 stepstruder. I was trying to print cube gears by Emmett thingiverse.com/thing:6073 (observe picture: Black print before fan, Blue print after fan). Anyway, I needed something easier to install, adjust, repoint and remove than Around the Nozzle Cooling thingiverse.com/thing:6173 by Scanlime or Ducted fan thingiverse.com/thing:5756 by Iwo, which are far better solutions than this. But from my understanding, I won't need it with the stepper extruder because of the 'cool' skeinforge plugin.

This is another cooling design, inspired by (but not directly based on) thing 5756.

I wanted to use Iwo's design, but I just upgraded to a MakerGear stepper plastruder on my Thing-o-Matic, and there wasn't enough clearance around the extruder nozzle to mount any fan ducts on the top side of the Z-stage. So, this design is a circular cooling nozzle that mounts around the extruder nozzle, just under the Z-stage.

It is fed by two 1/4" PVC hoses, attached to a fan mount that sits on top of the Z-stage, near the rear of the bot. This mount holds a 40mm fan salvaged from an old graphics card.

The overall airflow is very subtle- it's detectable with your hand, but just barely. But it makes a huge difference in print quality for small parts. In the attached image of two single-wall calibration boxes, both boxes were printed consecutively using the same g-code. The only difference is that one box had the cooling fan intake blocked.

This design is in parametric OpenSCAD, so it should be fairly easy to adapt to other nozzle types or fan sizes.

Note: This adds some extra hardware to the underside of your Z-stage. Make sure there will be clearance with anything you have sticking up from your build platform. I had to remove the nozzle wiper from my ABP. (The wiper wasn't working very well with my MakerGear nozzle anyway, so no big loss...)
