you best bet is to ignore scanning and just make it in openscad. Which is designed to work by building up basic shapes into a final model.
Put it this way - a week with openscad and you'll have a parametric model that works.
A month with photo based 'scanning' and you'll have a patchy model, the wrong size with lots and lots of post processing to do before you get anywhere close to a printable object.
You will also have to learn how to use a number of very different pieces of software - rather than one easy to learn modeller.
So despite the tile of this thread - yeah you do need cad :-)
Because even if you manage to get a photo generated model - you'll neeed to learn a cad package or three to tidy it up, hollow it out, make any bolt holes etc.
Whereas a short openscad script will generate it all in a convenient ready-to-print and easily alterable model.
have a look at this tutorial: http://edutechwiki.unige.ch/en/OpenS...l#Introduction
It really is as easy as measuring things and then saying what shape you want and where you want it :-)
This probably a better starter tutorial: https://peak5390.wordpress.com/2013/...enscad-basics/
The thing about openscad that really appeals to me is that no drawing is necessary and with a few basic commands it's surprising just how complex a model you can produce.Last edited by curious aardvark; 01-28-2016 at 06:57 AM.
