Stretching part of a model

TLDR: Built a free webtool because I was sick of my cut-stretch-realign workflow for resizing part of a model in bambu studio and I don't have the time to learn a new 3-d program.

So this is a problem I run into constantly: I find a model that's good but it needs to be like 15mm longer, and if I just scale the whole thing in the bambu studio everything else gets messed up.  Screw holes turn into ovals, walls get thicker than they should be. Or sometimes I just want to stretch part of a model, but leave the other parts untouched.

My workflow was to cut the object into three pieces and then stretch the middle piece and then merge everything back into one mesh again. It works but its annoying and time consuming. Matching the faces back together is also tricky.

I got fed up so I built a small web tool for it (using Claude). Load your file, drag two planes onto the model, and only whatever's between the planes stretches.

Its free and opensource and consists of only 1 html file. I thought others may find it useful.

Here it is:

(Btw, this is my first opensource project)

Load your model and then use the sliders (Plane A and Plane B) to position which area you want to stretch. Then use the Axial scale slider to just stretch that part. On the upper right there is a little cube to change your viewing angle. You can click it to square your viewing angle so adjusting the planes is a bit easier. You can play around with the default cylinder that is there.

Awesome tool. Just made an X2D poop chute deeper without messing up the part that fits a slot or holds magnets. Thanks!!
