The item is an RC battery tray.
It is for relocating the battery to the rear of the vehicle between the shocks for better weight distribution.
Below the battery (held by double sided tape) is a crossmember between the frame rails, hence the need for the slot.
Got it all figured out though.
Thanks for the tip on adding strength with the fillets @ChelanJim
Glad to helpā¦if I did. You had it already figured out before I got there!
But I am disappointed to not talk you into getting a 3D printer of your own. 
It is addictive!!!
No room
In fact, wife and I decided recently to turn the guest bedroom into a playroom for the kiddo.
His nursery doesnāt give much room for him to run around (and he runs fast).
Plus the guest room is bigger sooā¦
Thank you ds690! Stunned I didnāt even think of that
Kinda one of those homer simpson moments!
No problem. If youāre used to designing in 2d, it takes a while to think in 3d and use other planes.
hereās my kwik box
Jim showed me how the shell feature works, didnāt know what it meant!
The walls being a different thickness was on purpose but you are 100% correct that I did do a few sketches and extruded each one. And yes the fillet was done on the sketch. But the bottom and sides automatically joined to one body (I performed no extra action) so I guess I lucked out.
That mirror feature is going to be useful though so thatās new to me for 3D, but I use it often in 2D.
I donāt deal in 3D modeling so I thought the way I was doing it was a āhackā job. I didnāt know I accidentally performed the process correctly as Iām not afraid to go into Fusion and spend time messing with multiple commands.
But the goal of my question was āwhat are the proper stepsā.
Super informative video though for sure so thank you for taking the time to even do that - the 3D advice is lost on me though as Iāll never 3D print.
It was only after Jim gave me some specific advice about strength and wall-thickness (this piece is only 2.3" x 1.3" or so), that I gave up some interior volume to thicken the walls.
Ended up redoing it and it was like a 5 minute ordeal. I knew I came to the right section to ask about 3D solid objects.
Part arrived!
I had given him absolutely no instruction other than āmake it solidā
Came out perfect, naturally since I use calipers for measuring shit
Since I needed the clearance for the shocks, I opted out of drilling into it and instead used 3M double sided tape to hold it in place.
Itās a slow-moving crawler so itāll last like this for years.
Now we need to see it in action! The crawler that is.
Soon!
Iāve got parts laid out for my competition crawler buildā¦just waiting for one last set of parts to arrive this Tuesday and then I can assemble it.
This is from 2023, so I will understand if there is no recollection from that point in time. I still must askā¦
Where did you find those etched extrusions with standard and metric equivalents?

FYI, this is happening. Weāll definitely need to keep an eye on this.
Distressing for sure. There is a way to manually install firmware from a download, and there is a jail break firmware out there as well.
Been following Louis Rossman, watched his board repair videos for years before he began lobbying full time.
I believe in right to repair.
Also love the bambu ecosystem.
Hopefully bambu will allow users that want to divorce themselves from the ecosystem to do so and find their own way.
If this becomes an issue for anyone personally in their day-to-day operations Iād love to hear about it. Iāll definitely post when this hampers the my use of my 3D printer.
Sounds good. Weāre printing several hundred āthingsā (nda) for a local company here on our 4 bambu printers. We hope that this gets worked out and if that changes, Iāll post.
Will this change effect you ?
Thats what a X1-E is for , the secret projects.
