This is a rear…  Still raw and needs to be refined.

Here are two rears and a front on the right.

All five wheels, two rears and three fronts, (one for the spare).

I added the radius/fillets and then polished them up.
And a dry fitted front…

I decided a more modern set of calipers would not only look cooler, but also be more appropriate for the car with some of the other upgrades it is getting.  I made the Wilwood retrofits for the C3 Corvette calipers I made earlier.  They use the same pads.

I've been working back and forth and back again with 3D designing, old school machining and basic hand building to facilitate better fitting of the soon to be grown parts to help the fit of the end results.
I milled up caliper and rotor "blanks" out of resin to help check tolerances inside the software and to the physical parts I have.  I also had to draw up in 3D some of the kit parts I modified for spatial orientation.  Here's some screen grabs I took before sent the files off to Fraxional.

These are the tie-rod ends with adjusters for toe.  Brass and aluminum loosely assembled.

I got some more of my 3D parts from Fraxional over the weekend.    All parts are raw as "grown", but I have cleaned off the supports.  Here's a few.
Flywheel with pressure plate & clutch.  Small 153 tooth flywheel.
Front side installed in bellhousing.
New corrected Hewland rear transaxle cover.
 Engineered to mount with magnets.  (I had the bosses for the magnets grown into the part.)
Full engine & transaxle dry fitted together.

Half shaft yokes 3D printed by Fraxional.  The shafts are brass; the larger one has already been treated with acid for the color.  Just dry fitted together.

I took a shot at growing some parts myself.  Here's a valve cover.  It's hard to capture the details in the clear resin in photos.  I plan to cast copies in opaque urethane resin.

The alternator parts were grown by Fraxional, but I neglected to send one of the part files so the clear piece is the inner/center section that I grew rather than wait.

I made some design changes to the wheel centers and rather than wait for Fraxional to grow new ones for me I took a shot at it by doing a front first.  (My impatience; they have good turn-around times).  I can't get the quality that Fraxional does (at least at this time…) and so I had to spend a couple hours fine tuning it on the mill.  Not sure if this will be the final master or if I will go back to my original plan of having Fraxional grow these wheel parts.  Primer will help determine that path…
Doesn't look too bad with my aluminum outer rim on it though.

I grew the masters of the Wilwood calipers I designed but was not able to get the outsides to look their best without sacrificing the details on the insides where the pads mount.
I machined and hand finished the insides to accept the pads and to fit together.
Fronts on top, rears on the bottom.

Mark, what printer did you purchase out of curiosity? I bought a Epax myself a few months ago to print all my parts out for the pro mod.

This is the inside of the valve cover master.  While I designed it with mounting features they filled in when the part was grown.  So I milled those features in by hand.

I wasn't satisfied with the last wheel I grew so I redesigned a few parts of it and made a new one.  The front came out fine; it was the back side I didn't like.
It like the previous one required a good bit of post-machine work (it was designed to have that work done) and I think it is an improvement.

The valve cover pattern is done and ready to have a mold made from it.
Same for the calipers.

Once in primer I still was not satisfied so I re-engineered the wheel to be three pieces instead of two.
This is the new spoke piece as it was grown.
And then machined.

This is the rear section of the new rim design; it still needs to be final machined.

The U.V. resin is very hard and brittle.  That part did not survive the machining process.
I started growing a beefier part and realized I could probably machine one from scratch faster.
I was correct, made this from scratch and the printer is still running.

I grew a new alternator fan but the inside filled in, a common issue with this printer.
So I machined it out.

I had a bit of a setback when it turned out that the platinum based RTV I use primarily would not cure against the U.V. cured 3D resin from the printer.  Even after using the sealing materials that worked as barriers in the past, the molds were not curing and worse than the time loss was it making gooey messes on my patterns. That took many hours over several days to clean up.
I invested in some tin based RTV and that seems to be the right stuff for this resin. 
Here are the calipers and one pair of pads I'll use on the car.

Thanks Dave.

 

These are the resin versions of the valve covers.

With an internal mounting system to hold and align the magnets to the ones in the heads.

I redesigned the rear wheel to be three pieces like the fronts and restyled the back of the spokes to match too.  This is the raw 3D grown/printed master before machining.
 
And after…
(The black marks are index points for making the mold.)
