Fwd: convert STL?

mondo
Hi David,

Is it a bltouch bracket for an ender 3 you are looking for, or for some other printer? If you don't want to construct a new cad model, and you only want one bracket, it will most likely be printed solid infill. You are allowed to physically drill holes wherever you want. If it is for the ender3, there are plenty of printable brackets, assuming it's the original hot end. They normally use the same fixing holes as the hot-end shroud, so you may need longer screws. It is not an ideal arrangement.

To make the bracket, using cad, it is basically an 'L' shape.my process, would be based on  that angle piece being constructed by using two cubes, offsetting one by the wall thickness, and subtracting from the other. To get the profile shape, cut pieces away by subtracting more cubes, say. The fixing holes, lar3ry has explained. No need to worry about rounded corners, or any of the fancy stuff. Print the thing, use it, then decide if you really want to do something better. It may take a few iterations to get the fixing holes correctly positioned, and the correct diameter, but the bracket can be printed in a fairly short time, so don't waste time initially making it look pretty.

Best wishes,

Ray

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.

Thanks,

David

What resource are you using for the bracket? Is it open source/thingiverse/other?

I tried the "ground up" approach.  I sucked.

Antclabs have full documentation on bl touch, including fixing holes,
etc https://www.antclabs.com/manual

Could find no reference to an OpenSCAD model in their manual or on their
website.

Why did you expect references to openscad? Their manuals contain the
dimensions you need to make your own bracket, and connection
information. You should be able to apply that to the openscad code I
gave earlier, or any other design you may have. If your firmware is
Marlin based, you will enjoy altering it to take account of your bltouch.
