123D Design: How To Scale Down Measurements Without It Scaling Down The Wall's Thickness

[Anonymous]

I have a small tool box with drawers to fit my Ender 5 Pro 3D printer. The original designer made the tool box so small that I can't even fit two fingers in the drawers to grab a hold of the tools stored in them thus made the user have to pull the drawer out completely and just dump the tools in order to grab them.

   I scaled up the tool box's frame which was no problem using 123d Design's "Smart Scale" tool which even if it also scaled up the thickness of the frame's walls, that was perfectly fine as well as having scaled up the thickness of the walls for the drawers, but I have to use one of my existing scaled-up drawers to make my last drawer which is considerably shorter in height thus when I scale down the height of my drawer it also made the floor of the drawer nearly paper thin whereby a light push of my finger will break through it

  So after having scaled the width of the drawer, how do I scale down the height (the length's of the drawer stayed the same as the original designer had them) of the drawer without it botching up the thickness of the walls?

  I tried using Cura setting before slicing to make the bottom layer thicker but this seemed to do nothing since the drawer still had the same paper thin floor after printing it

I also tried using just the "Scale" tool and choosing both the "Uniform" and "Non Uniform" options but either way they still changed the thickness of the walls.

I also tried converting the mesh into a solid to see if that somehow did anything to my advantaged but nope it didn't... at least not by how I tried to do it after having converted to a solid

Your grief stems from the converted STL.

moving a tab worked, it was a very simple mod.

This new venture needs a Fusion model from scratch. This was suggested earlier.

Make Frame as a solid block, cut the holes with solid block drawers.  

Shell the drawers, with the wall thickness as required.

Might help....

Ok so changing the height of this drawer while yet keeping the same floor thickness, is not an easy modification or isn't even an option provided by the software of either 123D or Fusion360? Which one is it?

I mean, I dont know. I'm just asking since as you know from our other recent help session, I'm not going to make a whole new object from scratch, and regardless of what anyone says would be easier for a complete beginner to do versus what should be a much simpler or somewhat simpler process of just making the wall/floor thicker after having changed the height

There just shouldn't be any good reason why AutoDesk didn't provide a reasonably simple way of keeping the same thickness of a wall when changing the measurements of an object. However I'm sure someone will try to say there is a good reason lol 🙂

Some random thoughts.

-It's an easy modification. (in fusion, don't know anything about 123)

-fusion sucks at modifying .stl files.  (which is why everybody is trying to get you to remake the thing in fusion.) 

-to modify the brep you might try selecting all the top faces and doing a "move face" , moving them down.

-you might try mesh mixer, which is great at modifying .stl files.

Thanks for trying to help.

   I just ended up taking one of the floors of the drawers I had stopped printing right after seeing the floor wasn't being filled in very thick and glued it to the floor of the whole drawer I had printed with the paper thin floor in it.  Was quicker than for me (maybe not others) to design a new drawer and it will definitely do the simple job of holding my spare nozzles and tip cleaners

  Well hope you have a good evening and thanks again

Let’s see if I got this bit right, you have converted from Stl, a file that needed mods to most of it, but didn’t know that at first.  First mod worked out.

second mod - 

You got no joy from Fusion scale tool, didn’t mention any others,

got no joy from Cura, and ask a Fusion forum.

Fusion did not show you the easy button, (it’s there if you think outside the box - a little)

and any suggestion of starting such a simple model in Fusion to use Fusion tools is a flat - no way - why should I.

But don’t panic I used a failed print to fix it, and didn’t need Fusion at all to get there.

Can’t see why it is Autodesk’s fault.

Hi,

please share the file.

so there is a basis for possible courses of action.
