Just for a giggle I printed another Marui Samurai in one piece from the assembled CAD file .

Ultimately it failed as two wheels came out flat on the bottom.

Before you judge too harshly look at it next to my white Samurai runner

Very good idea :). You just gave me another idea for the Nichimo :)

Found another free 3d scanning programme to use with the Xbox Kinect scanner , this one is way better ,it's has no limit to the polygons so you get way better detail . This print was then smoothed by painting on 3d printer resin and curing with a UV lamp then sanding to remove all layer lines , after sanding it's the been painted .

Looks great Dadio!

What scanning software are you using? I am picking up a used Kinect today and am looking at Skanect as an app.

I have been experimenting with photogrammetry lately, but it isn't working for me for the fine details.

I tried photogrammetry but never got the results seen on YouTube :roll: , the first head print was done with Skanect free version , it limits the number of polygons in the model so when you print large scale it's very low poly looking , if you pay for it it's better .
The second head was done with Reconstructme , it's a simpler process to use than Skanect and is not hobbled in the free version either .

Thanks. I had read of the limitations of the free Skanect, and Reconstructme had come up multiple times in my reading. I will look into it.

I feel with Reconstructme the limitation is the Kinect scanner , it's designed to detect the movement of a human size target object , I just can't get any more detail than you see in the second head and for scanning small things it's really sketchy .
Things to do to get the best scan are .
1 being able to rotate the target object or person exactly on the spot , I found a swiveling bar stool best .
2 lighting , you need good ambient light .
3 the surface of the object must not be too reflective or shiny , Lexan bodies are terrible to scan , talcome powder dusted over shiny surfaces or a face powder on your face , if you have a shiny bald head it will just a hole in your head scan .
4 distance to the scanner , I found between 1 and 2 feet is the sweet spot .
5 if your doing a head then start scanning the back of the head , at the end of the scan it has to stitch the begining and end together and it can make mistakes , rather than ending up with two noses it's better to have two locks of hair at the back of your head .

While clearly undesirable results, both of these sound hilarious to me. 🤣

Started remodelling up gears from scratch for the Dogfighter 834b , did a far cleaner job this time and I've got them being printed by Shapeways now , if they turn out good I'll add them to my shop .

Then moved on to the Delta Desert Dog conversion set , again I cleaned it up a bit and stuck it on Shapeways , it designed as an artists impression not a direct copy and is compatible with the stock chassis .

For the suspensions, sometimes, it is a bit funky... I had to set limits on some joints other wised the whole stuff get in weird impossible positions :-)
