I purchased a KHR-3HV (black edition) Humanoid robot from Kondo in 2011. At the end of that year, I saw Gundam Head Collection No.1 toys came out in Akihabara and they seemed to be the perfect size for my KHR-3HV. The collection had been out for a few months, so I bought the RGE-B790CW on spot first, and slowly looked for others when I was in Japan. With a little modification of the original KHR-3HV headpiece, these Gundam heads fit nicely on it as if they were made for my KHR-3HV.

Recently, I discovered that Kondo has released many design diagrams including parts for KHR-3HV. One of the parts I wanted to custom the most is the chest plate – the front cowl as Kondo calls it.

Inspired by Gundam RX-78, made a quick mock-up on Tinkercad.
My brother brought a Phrozen 3D printer home for me to use. Learning to use a new 3D printer is like taming a wild beast, especially this is an LCD resin based printer which I had never worked with before. A few notes from my brother (the master) to me:
- Use ChiTuBox for calculating supports (.stl), and Asiga for slicing (.slc).
- Avoid horizontal lines at all cause, ones that are parallel to the print plate
- Set thickness to be 0.05mm in Asiga because it has to match the resin used
- send the .slc to the printer
Since I have a lot of straight lines in my designs, no matter how I tilted the model in ChiTuBox, I would have lines that are parallel to the plate. Therefore, there were warping at some of the edges. I think the resin based printers cares more about the interior structure than filament printers. The warping could also be that I didn’t scrap the model off right after it was done. I guess I will find out when I print more. The print took about 8.5 hours (506 mins) which is much longer than printing the same model on a PLA printer. However, the detail is definitely superior @ 0.05mm with Phrozen. I miss my long-time partner, my well-tamed beast, Makerbot.
This was a great first step, Tinkercad skill levelled up!
