After getting delayed from late June until yesterday, the "Battle at the Barn" went off really well and I finally got to hand out the sword trophies I made!

Congrats to all of the winners!

I managed to snag one for myself and it will be hanging on my wall shortly.

Thanks go out to Gary Phillippe & Tommy Barker working on the track (it was damn near perfect by the end of the night, despite the literal rough start), and to Curtis Trippensee of Meadow Ridge Trains and Hobbies for giving us a place to race!

I am always proud to supply the trophies and hope to keep doing so for many more years.

Guess what I've been working on...

Several things, actually.

The first thing out of the gate is a new version of my 'Bullhorns'!

This new version solves the one failure mode that has been reported to me, the part was splitting at the mounting screws. I have a history of analyzing part failures, so I did some testing to replicate it and figured out that it was due to overtightening the mounting screws.

I tried many different designs but never really got anything to work well enough that I felt confident that it was actually better. Then I bought a new printer and a solution that I had was finally viable. I bought a Snapmaker U1, and it allows me to print with multiple materials without filament changes. That means I can use flexible material and hard material in the same print.

After more than a few versions, I finally have a version that I'm confident is a huge jump in durability. It now has hard mounting points while keeping it's flexibility. A few customers have already received this new version to test and I haven't heard of any issues, so I'm finally giving them an official launch!

Grab the new version here:

If you have a shop and would like to carry them, don't hesitate to reach out to me and we can figure out a deal.

My 'Bullhorns' are made of a durable and flexible material that will hold up better than other, rigid materials. Unlike other solutions, the 'Bullhorns' actively pull the nose of the body down onto the bumper.

I finally got around to making a set of custom pit stands for a very important customer...

Myself!

I didn't get quite as ambitious with these as I wanted (I couldn't figure out how to model the features), but I'm pretty happy with the results.

If you're interested in getting some made up, just message me and we can get started!

Time to say thanks to a couple of customers!

Thanks to Tyler Welch for the pit stand order! These were a fun challenge for me and were the first pit stands I've made that had five colors and were printed off of a machine that only has 4 colors of filament. I spent quite a bit of time on them, but I also learned quite a lot and can produce another model with the same results much faster now. Congrats on the 'Barnado' win as well! I hope the trophy brings a smile to your face every time you look at it!

I also have to thank Patrick Keller. While his pit stand was a little more basic, they all have their challenges. While it may have a simpler design, it still turned out great and I hope you get many years of use out of it!

Also, thanks to everyone who has been ordering my 'Bullhorns' on eBay! They have been selling better than I ever expected! I am working on a new version that is attempting to remove the one failure mode that's has been reported back to me by a few people, which occurs when the mounting screws are overtightened. This crushes and stretches the material, leading to failure. The new version removes that failure completely, but may introduce others and needs thorough testing before I release it, if it gets released at all.

So once again, thanks to everyone for your support! I truly appreciate every purchase.

Another order completed!

Thanks again to John Blankenship!

Believe it or not this one was a bit of a challenge. John's car number has a green to yellow gradient and at first I didn't think I would be able to do it. Then one night I had an idea and a few color tests later it looked like it was going to work! I sent my test prints to John and he picked the one he liked the most and I went with it. The process turned out to be fairly simple, but I'll save the design talk for another time.

I do think the gradient would have turned out a little better if I had a slightly more opaque yellow, but I didn't have any on hand.

That being said, I am excited to try this again in the future and even try new things with a similar process. This method will also allow me to 'cheat' and get more than 4 colors!

For example, if you want your pit stand to have red, white, blue, & black, I should be able to use those colors to also make pink, purple, various greys, and darker reds & blues. Currently, the process I use for gradients will only work on the flat surfaces, but I should be able to mix colors without to many constraints.

So, who will be the first person to push my new limits and beyond?

Just message me to get started!

I just finished up a few more custom pit stands!

The first two are actually the 2nd and 3rd stands that I have made for Hobby Pro Center because the moment Shaun Zimmerman saw the original, he bought it! I didn't actually intend to sell it, but Kyle Harrison told me that if someone wanted to buy it, let them!

Speaking of Shaun Zimmerman, after buying the first HPC stand, he ordered another one but with his awesome "STZ" logo that was designed by his father.

Thanks for the order, Shaun!

If you would like to get your own custom pit stands, message me and we can get started!

I'm still offering them for $30 for one and $55 for two, plush shipping.

I have another order that I will be posting as soon as the customer gets them. I like to keep the final result a bit of a surprise and can't wait to share them. I tried something new with them and I think it turned out pretty good and will be even better with different colors.
