WinBook TW700 Tablet Cooling Stand

thingiverse

This was a "Cool" little project. It helped me learn how accurate my Flashforge really is. I recently bought a WinBook TW700 (7 inch) tablet from Microcenter. This tablet comes with WIndows 8.1, and was only $60 (open box). This tablet works pretty good, but it easily over heats, and then shuts down, so I designed a cooling stand with an integrated fan. The Winbook is currently used in conjunction with a Monoprice 12 x 9 graphic drawing tablet to allow my kids to draw freehand images. The tablet can easily handle the drawing tablet hooked to it. The Winbook is also attached to a 24 inch 1080p monitor, and has no problem displaying images. But again, it overheats, and turns off, so cooling is a must. This stand leans the tablet back at 60 degrees. The tablet can be found on the MicroCenter website at http://www.microcenter.com/search/search_results.aspx?Ntt=tw700 The integrated fan, I found on Amazon for $13 ... see webpage https://www.amazon.com/AC-Infinity-MULTIFAN-Receiver-Playstation/dp/B00G05A2MU/ref=sr_1_1?ie=UTF8&qid=1482353118&sr=8-1&keywords=AC+Infinity+MULTIFAN+S3%2C+Quiet+120mm+USB+Fan+for+Receiver+DVR+Playstation+Xbox+Computer+Cabinet+Cooling What i like about the fan, is that it is super quiet, and no vibration transmitted to the stand. It has a switch on it, so it can be turned off, or set at Lo, Med, Hi. Also since this fan plugs into the 4 port splitter, it only runs when the tablet is "On". I printed this out using a Flashforge New Creator Pro. The filament used is MicroCenter's Inland filament 1.75mm PLA,, Purple. at only $15 everyday price (I picked it up at the store). I find this filament is comparable to HatchBox... typically runs 5C degrees lower than HatchBox PLA. I ran the nozzle at 225C and the bed at 65 C. I am simply amazed at how dimensionaly accurate the Flashforge is. The right side of the stand is a mirror image of the left, except for a cut out provide access to the buttons. The top piece has slots that align with the cable inputs... micro-usb-power-port, USB 3.0 port (runs to a USB Splitter with 4 ports), stereo plug, mini-HDMI port. I did try to print out pegs that could be inserted into square holes on the left and right side pieces, but this became difficult to do, so I eliminated the pegs. I left the square holes in the left and right side pieces though (for a later improvement, if I ever get around to it). The bottom piece has a peg on either side of it to help with assembly of the side pieces. However, once the fan is installed, those pegs don't matter. Both the bottom and top pieces are reduced in size by 0.5mm on each side (where needed), to provide clearance to ease assembly. The fan screws were just long enough to be used to attach it to the stand, so I did not have to buy additional screws for attachment (I did have to remove the rubber grommets though). I also had to remove the front grill on the fan to get the screws to reach. The fan is low powered, so testing with my fingers, it kind of tickled so for me not an issue. Other Info... Printed in layer thickness of 0.3mm Using ReplicatorG Sailfish. 3D model created using SketchUp Make (free software). I also tried 45 degrees, but the fan's thickness made it touch the desk surface below, so it had to be skooted up to the high end of the stand... thus the cooling effect would be diminished.
