Hello Everyone, Before I start working on it myself is there any available file of the core of the XRP Chassis. Meaning only the stack where the chip and the batteries are located? I am trying to do an assignment where my students design their own chassis and being in 8th grade they struggle a bit with the tolerances on measurements. ---

Hello pp-belen, What program are you using to do the design in? The reason i ask is I’ve been doing some experimenting in tinkercad with modifying the frame. I’m working on a video that shows the process to create a shortened frame, similar to what was shown earlier on the forum, however that video isn’t quite done yet. ---

Hey there TFossDK, I am having the boys work in OnShape. They did some rudimentary lessons at the beginning of the year and I have been having them practice. Because of that I will be working on that in that ecosystem. ---

I made an stl one early on int tinkercad thinking the same thing but it was the early v1 chassis design. I ended up not using it, but I could certainly send the file. I eventually decided on the existing chassis rail mounting system offered enough opportunity for design and build for the kids. ---

Is this what you are thinking @pp-belen? I can’t attach .stl files to this page, however if you want i could email this file over if this is what you are looking for. Also as another option, I can also export it as an .obj file as well. ![battery tray and board mount](https://canada1.discourse-cdn.com/flex011/uploads/xrp/original/1X/f640ebdf68a1fd43d692a474757423f03e1b14c6.jpeg) ---

Are the 3D files around for the current chassis, I found some but they were the earlier one with the different battery door. ---

Yes this is exactly what I am looking for! Did you chop that up on a slicer? ---

I actually used Tinkercad to cut it up. I’ve been using Tinkercad more recently and I’m finding it is actually pretty good for modifying .stl files. To accomplish this, I imported the frame and then drew two of the “Hole” boxes around the two sides i wanted to remove. I then joined those two boxes with the frame to remove the parts that i didn’t want.
