I have an STL for a sensor mount (BL Touch) written for a CR-10 3D printer.  However, I need to slightly modify it for use on a different printer.  One screw hold needs to move.  I do not understand quite how to get from point existing to needed.  It was explained to me once but apparently, I just didn't get it. Any clues, tools, magic tricks I can use to get there from here, please? Thanks, David

If the existing hole needs to be not there, create a cylinder, move it to where it plugs the hole, and union() it with the imported stl. Then create a cylinder, move it to where you need the new hole, and difference it with the imported stl. I know it's a general answer, but it was a pretty general question. -- Sent from: http://forum.openscad.org/

David, do you have only the STL file or also an SCAD file from which it was created. The answer is very different in each case. The answer to the first is what I would consider a work-around, while the answer to the second is going to be more elegant or more appropriate.

Only an STL.  Oh yeah, an SCAD file would be easy in comparison. :) On 12/26/20 4:07 PM, fred via Discuss wrote: > David, do you have only the STL file or also an SCAD file from which > it was created.

I printed all those last week.  Not recommended for actual use. For one thing, "slide" has only one grip point.  And they are -very- small.  <sigh> On 12/26/20 4:48 PM, David wrote: > > I tried the "ground up" approach.  I sucked. > > > On 12/26/20 4:40 PM, fred via Discuss wrote: >> I did a quick Google for the parameters you've provided.

Tried several from thingiverse.  Also tried modeling the CR-10 (metal) one that comes with the Creality kits.  While it was not wonderful, the CR-10 model could be used in a pinch on an Ender 3, for example, if you didn't have a real, metal one.  My attempt at duplicating it with changes never got past the drawing board.  I'm very new to OpenSCAD.
