Cross Flow Fan Bracket Flashforge Creator Pro PowerSpec Pro

thingiverse

This is a cross flow fan bracket for a Flashforge Creator Pro, PowerSpec Pro of similar printer. I'm sure it could be used for many other printers. It uses this fan: http://www.amazon.com/gp/product/B0059BCWGU?psc=1&redirect=true&ref_=oh_aui_search_detailpage UPDATE: Version 12 added. It includes the 2 notches on each end to make room for glass bed clips, and is also 140 tall, to allow the fan to draw cooler air from the bottom of the printer. Also, as Mark keenly pointed out, this is a 12V fan. I used the adjustable regulator below, and connected it to the 24V supply. +12 going to the Fan, and taking the switched ground from the mightboard extra fan control to allow the board to turn the fan on and off. http://www.vellemanusa.com/products/view/?country=us&lang=enu&id=350481 A little disappointed, as it doesn't move as much air as I thought, but seems to help. UPDATE 3/5/16: Stuck a diode on the fan, as it was backfeeding my other head cooler. Also, the fan controller I have just can't handle the current draw, and wired the fan directly to the +12V supply, without the fan controller. I've been running if full speed anyhow. I've needed to bump up the voltage twice to get this going, but am now very satisfied with it. I use it all the time. While I love the coolers designed to ride along on the head, I often need a little more cooling, especially when I am printing hollow shells (no infill), to keep the edges of the shells warping up. I printed a couple of muffin fan brackets so I could hang fans on the front of the printer, but it blocked my view to monitor the print. This you can velcro to the side of the printer, and it neatly fits close enought to the bed and high enough to make a gentle breeze across the bed. You can of course drill some holes and screw it directly to the side of your printer. You will also need to drill a couple of holes on the top to hold in the fan. I just used 2 flat heat 3mm screws on opposite corners of the fan. I thought I had it perfected, but forgot to take into account the thickness of the velcro. So I had to trim the corners a bit to make it fit, due to my using corner clips to hold my glass bed on. I left the top off on the one end, to allow the printer nozzles to fit for my dual head printer. As this is my start position. But I have provided an adjusted version. To give a little flexibility, I have provided a couple of flavors. 1) The original version, which if like me, you might need to nick 5mm x 20mm off of the 2 corners to allow for corner brackets on you bed. 2) A 5mm trimmed version of the original, so you don't have to do the above. 3) A really tall version, so the air gets sucked in from lower inside the printer body. This is 160mm tall, and you can slice to taste. 4) Same as 3, but with the 5mm slices off the end to make room for corner brackets. Designed in AutoDesk Fusion 360 Enjoy Print Settings Printer: PowerSpec Pro (Creator Pro Clone) Rafts: No Supports: Yes Resolution: .2 Infill: Anywhere from 10% to 30% Notes: I typically print 4 top and bottom layers, 4 shells and 30% infill using Simplidy3D as my slicer. I'm sure this would print fine with 2x2x2x10% It's a 10 to 15 hour print depending on your tuned speed
