2020 Corner Bracket Remix

thingiverse

I really liked TheStapler's beefy 2020 Corner Bracket design. But...I also don't like to print with supports if I can help it. So, I modified the original design to make it so no supports are required. This of course means all the credit goes to TheStapler for the original. Here is what was changed:One of cross brace supports was widened such that it touches the bottom of the print surface now. I didn't do that with the other 2 in part because my CAD software doesn't allow easy chamfering of curved edges and the widening does make it look a slight bit different. If you don't know what you are looking at/for you probably won't even notice. But, if someone can chamfer curves easily...maybe they'll complete this and do the other two. Anyway...because of only 1 side being done this way, it MUST be printed down (basically in the orientation the file is in). This means you can rotate it around the horizontal axis, but do not rotate around the vertical axis.3 of the locator braces where chamfered on the lower side to 45 degrees so there is no longer any overhangs other than the bolt holes which will print without supports.3 of the bolt holes on the bottom have a 0.2mm layer over the transition from the larger washer hole part to the smaller bolt hole part (so you can't see all the way through them when viewing the STL file - this is ok). Doing this removes the need to have supports in the bolt holes and with the layer only being 0.2mm, it is incredibly easy to just push your bolt through it.I've now printed 8 of these without any supports and all of them turned out great. Wanted to post the remix both as a thanks to TheStapler and to give back to the community.I used Cubic for my infill (vs Honeycomb, but I think they are nearly identical), 35% infill, 3 wall layers, 0.2mm layer height. So identical to original except the infill difference.
