HO Scale Modern Truck/Tractor Fenders

9/14/2016 update!  I have added a couple designs at the bottom, and some some new pictures supplied by my customers.

4/1/16.  Another item I have been selling a lot of, truck fenders.  Not my era, so any finished models I show are not mine, and I will give credit for picture I show that are not mine.  I have several different fenders available, and I will address them one at a time.  In most cases, I will picture them primed, but they will be shipping in natural ABS.  They don't photograph well in their natural state, and you can't see the flaws.  I will give a discount to people who have used the fenders, and will let me use their photographs.  Here is a view of my original assortment.

Single Half Round Fenders
These are $1.00 a pair + P&H. (U.S. postage and handling is $3.50).  I can get a lot of these in a small box, and ship first class with tracking.

Double Fender (the ones in the upper right)
$1.50 per pair + P&H

Marsh Buggy Track, HO Scale, 3D printed

 I don't do a lot of promoting of my side business, but I have had several calls for these today, so I thought I would get a post up with all the pertinent information.  If you have any questions, please ask, and I will edit this post as needed to add any needed information.

Justin Grim mentioned on a Facebook group that he was looking for Marsh Buggy tracks, and could not find any.  I thought it might be possible to 3D print them, and that, at the very least, it would be a good test for the printer, and my design skills.

I found several manufacturer web sites, and was able to get some dimensions to get started.

Here is the first drawing; several adjustments were made to this before I got a decent print.

 Here is a side view of the three sizes I have printed,  The bottom one is reasonably close to prototype size for HO scale.  The graph paper in the photos has 1/4" squares to give you some dimensions to work from.

 The top view.  The medium size one is 75% of the full size one, and the small one is 67%.

 I did minimal clean up on these before I sprayed them with primer. It is difficult to see the flaws until some paint is applied.  This is the largest size, and I sell these for $22.00 per pair, plus postage and handling, $3.00 for U.S. addresses.   Each track take 2 hours and 39 minutes to print.

  

 The medium size unit is going to take a little more cleanup, but certainly takes a lot less material and a lot less print time.  I sell these for $12.00 a pair plus postage and handling, but keep in mind, they are going to require some cleanup. 

The smallest size sells for $10.00 a pair plus postage and handling, and is going to take the most cleanup.  I intentionally took this picture from the bad side, so you can see what you have to deal with.  These are printed in ABS, so a sharp hobby knife and a file will clean them up rather fast, but it still take some patience and skill.  I highly recommend that you prime them before trying to clean them up, as the paint will make things show up that you might not see otherwise.

Here is the one Justin Grim is building.  He added several details to the tracks.  Note that this is a long reach excavator.  It really fits the large tracks and looks right to me.

Of note, the track pontoons are not solid.  This is a shot of them during the printing, and you can see the fill is mostly air.  If they were solid, they would probably take 8 hours to print, and cost a lot more.

Here is one I am building using a Wiking model I picked up.  It is not a long reach model, an that is why I made some scaled down tracks.  You can also see in the picture, that until there is paint applied, it is hard to see any of the flaws and/or details.
