TB6600 40mm Fan Case

thingiverse

This is a case that demands the kind of exceptional TB6600 stepper driver controller, like the one available on eBay: http://www.ebay.com/itm/CNC-Single-Axis-TB6600-0-2-5A-Two-Phase-Hybrid-Stepper-Motor-Driver-Controlle-F5-/291714731792?hash=item43eb8d8f10:g:e6oAAOSwxvxW70iX These drivers can be significantly enhanced by referring to my posts on this CNC forum: http://forum.planet-cnc.com/viewtopic.php?f=9&t=1107#p13517 Essential improvements include the requirement of a fan, specifically a 40mm fan. Any fan will work for this case, and 40mm fans in various voltages are available from AliExpress.com and can be run directly from your stepper driver input voltage. The fan is secured to the outside of the case using #4 machine screws and nuts (I used 11/16 long screws, but that may depend on your fan's thickness). Printer Settings Printer: Custom CNC and 3D Printer Rafts: Yes Supports: Doesn't Matter Resolution: 0.2mm layers Infill: 100% Notes: You can probably get away with much lower infill settings. Some bridging errors may be expected if you experience bridging difficulties. Rafts are necessary for ABS to prevent warping of the corners.
