CTC Mightyboard Standoff

thingiverse

I decided to create a Mightyboard Standoff for my CTC printer to make removing the motherboard easier. You see, I'm a 'tinkerer', so I have already removed it once to install the Z axis rail mounts (http://www.thingiverse.com/thing:692085), and again to install the missing Mosfet to control a PLA fan. And I'll be removing it a 3rd time to install the parts for the missing LED Strip controller. (see this thread: https://forum.simplify3d.com/viewtopic.php?f=8&t=1586&sid=ab60ac854627aafbed495d0f07c24a4a&start=10#p6269 ) So I didn't really 'need' this part, but it sure makes things easier if you want to pull your motherboard out for any reason! I created two versions, you only need to print the one you want to use. The "Original bolts" version has 4mm thru-holes, for use with the 'stock' mounting hardware. (Long M3 bolts through the standoffs and mightyboard, washers and nylock nuts on the bottom) The 'threaded' version is designed to screw M3-12mm screws from the top and M3-10mm screws from the bottom (Note that you may be able to get away with M3-12mm screws for both sides, assuming you're re-using the metal washers on the inside of the printer and the two red wafer washers on each nut when mounting the motherboard. The standoffs are 17mm tall) I also took the opportunity to move my wiring harness UNDER the mightyboard controller, making the overall appearance under my printer much nicer. (Not that you can see it under the bottom cover anyways, but oh well!) [see last pic] ***NOTE*** Make sure you LABEL ALL THE CONNECTIONS before you remove them. ;-) It will make re-assembly much easier!!! Print Settings Printer: CTC Dual Rafts: No Supports: No Resolution: .3mm Infill: 50% Notes: Nothing special - you should be able to print it in any plastic that you want, as it doesn't get very hot down here. If you do print it in ABS, remember to scale it up by 1.7% to account for shrinkage, or the standoffs won't line up right! Although if you choose to print the 'threaded' version, you should use 3 or 4 shells to give the screw threads something to grip on. ;-)
