Summary

This model is designed to be a 3D printed accessory for the FT Mini Pietenpol RC foam board airplane designed by Josh Bixler of Flite Test. Josh designed a Model A engine for the Pietenpol using Flite Test foam board. While this works to capture the basic look, Josh was looking for something a little more detailed. This is my first 3D model designed specifically for 3D printing.

Can you tell the weight in grams or OZ for each piece?
Thanks,
Wes

tried to download the file
i get a certificate trust list
what next
i even sent a tip

(not picking on the model, pointing out what is wrong with the interesting attempt)

If your a rivet counter, the head is wrong as it should have been molded with a radi like near the radiator. The model A engine was a beefed up model T engine wiht outh the attached trans of the T. The return water pipe should go to the side instead of the top. The big hose should be coming out of a goose neck. Basically for the plane the front end of the car engine points to the rear of the plane.

Hi Sponz,
Thanks for putting up the 3D file for the model A ford motor.
Just out of curiosity, did they cast a "special" head for the motor?

I assume that they did an aluminum head and ran a mag or a couple of mags
for ignition. It is great to see some of the "AV" conversions on old Ford Iron.

Thanks to your effort I'll have to print one of these out for my FT Pietenpol.

I have Ford Model T cars , one Speedster, one touring and those motors were
Really customized for aviation use. Thanks again for your time and expertise.

The ignition on a model a is a distributor that sticks out the top of the head. Brass strips (spring loaded) were wedged between the flatenedd distributor and spark plugs. The cap would have to be printed in a seperate piece becaus of how ford made it. It was black bakelite and the engine is olive green.

Hey jobobeda,

Not really sure on the head for the engine used on the Pietenpol. I don't think it was a custom head, but I'm not positive. I did use some photos of a couple different engines as a source to make the model. It is only semi-scale, to fit with the foam board version of the aircraft. I was on a pretty short timeline to get the model done in time for the kit release. This was also my first attempt at designing for 3D printing.

Let me know if you print it. Thanks.

Have you thought about making the engine block overhang smaller or closer to a 45 angle to eliminate the need for support? If not, you could separate the top and bottom sections of the engine block. Also, in the interest of support free printing, the exhaust headers could potentially be separated onto a plate you glue to the side so they can be printed in a vertical orientation.

Thanks for the great feedback. All great suggestions. Modeling for 3D printing is a whole new ball game for me. I'm learning as I go. This was a time sensitive project for Josh Bixler at Flite Test so it was a bit of a rush job and also my first 3D printed design. I plan to add even more detail to it in the future and will look at slicing it up into smaller pieces to eliminate the supports.

On a side note, the original version of this model was all one piece. Needless to say it was a pain trying to get a print to work that way. ;)

Printed out perfectly thanks!!

When I try to process the radiator stl it has gaps and will not print correctly. I use simplify3D and this is the first time I have had issues. The models are great keep up the good work!

Can you elaborate on where you are getting gaps? I am using Simplify3D 3.1.1 and have printed this file 3 times with no issues. I am new to 3D printing, so please bare with me as I work out any issues during the learning process.

I just processed it with slic3r and it was fine. I'm using simplify3d 3.1.1 as well. It must be a setting i'm missing. I'm still trying to find what happened.

I posted a pic in 'I Made One'

mesh -> seperate connected surfaces will fix the problem by seperating multiple intersecting shells of one stl to on shell in multiple stl's which print fine
