<p class="MsoNormal">Today I received my shipment of some 3D printed motor mounts a Rock Island U25B project. The motor is Kato’s HM5 and the chassis is Bowser. I have a few of the Stewart U25B kits, then after Bowser purchased Stewart Products they made
an improved chassis which is in the image below. I purchased more of the chassis parts from Bowser and since they parts provided were not that great I decided to re</p>

<p class="MsoNormal">These are printed on the HP JetFusion 3D printer. Material is Nylon 12 (PA 12). I ganged up two together linked together and had 5 printed. Cost total was $37.90. $6.50 for shipping from France. I uploaded the print file on April 6<sup>th</sup>.
I think that’s pretty good. I had also uploaded to another 3D printer service and they complained about the part arrangement and threw a ISO standard related to aviation parts at me so I just cancelled that order and waited to see how these turned out.</p>

<p class="MsoNormal">This is a close-up view of the parts. The surface is grainy, but the part is strong. The HP printer is a powder based and requires some post processing when it comes out of the printer. The legs for the screws need a clean out so I just
use a drill </p>

<p class="MsoNormal">This is a view of the three main sketches to make this. May not look like it’s all there, but this is all it takes. There are two configurations of the parts – one is longer than the other. Just a matter of useing the sketches to build
out the surfaces of the part.</p>
