I measured the holes that the pegs will fit into (as well as I could) and they appear to be small. This isn’t a big deal because we can easily take a knife to the dowel or a drill to the bones. However, I have modified the model to increase the size of the peg holes. If you have started the prints, do not start over. However, if you haven’t started anything yet you might try the newer models (femur-hip-right/left-front/back-0817). Folder includes date and says something like “larger pegs” on it.
Anything that is on the front or at the “green” joints will take the impact when the racer is stopped by the hay bales. Is it possible to print something for those joints using Ninjaflex or TPU or something else a little more flexible and less brittle?
Or design it so it launches a skeleton head into the air on impact.

We might be able to rig hands that would flip and catapult a skull on impact. @John_Marlow, I know you have hand models, but do you have feet models?

Feet with dangly toes would be a fun addition
I was thinking feet on the front with a sort of cantelever that attach to rods that throw a skull in the air.
I assigned color names to each joint. There are six discrete geometries (plus mirror images) and colors were the easiest way for me to identify which bone joint will go in which location.
The bone models shown on here are not scaled, and the color refers to the joint location - not the color in which it will be printed!
Today I modeled the blue joint. This is one of the tougher joints and if the fit is close, I propose we take a dremel to it! For the red joints we have the knee and hip ends of a femur. We also have a consolidated knee joint with both a front and back side that can be attached to any straight run of tubing.
I’m concerned about the orange and the cyan joints because of interference from the two hinged panels
If our flying skull crosses the finish line first, does that mean we win? Or does it disqualify us?

@CaryF300 - have you had a chance to print this blue joint yet? (It’s called blue for the joint name, and the file name). I’d like to know if it’s approximately correct before I embark on the magenta joint. These are the more complex designs … Thx.
Sorry Chris, I haven’t I didn’t realize the file was available. I’m headded out of town, but will print it as soon as I get back home on Tuesday.

I have also added the magenta joint. Fingers crossed.
This should be obvious, but I don’t see any reason to print both the RHS and LHS joints until we believe they fit.
Thanks for all you do!
If getting all the angles perfectly aligned with the frame is an issue I think it would be fine to just have individual bones that butted together near the joint, the knuckle could be smaller like stick out an inch.

Do you want something like this? Perhaps on the rear two hinged panels, sort of like tail lights? (but not positioned to interfere with the “pusher”)

That looks awesome!

@rlisbona - Please decide how many of these you would like and where. I suspect they’re going to take a long time to print and a lot of filament.
The skull is about 4" tall x 3.5" wide. Sounds kinda big but it is roughly to scale in this mockup and I think smaller would be just too small. I also had concerns about the jaw being too thin and weak at smaller sizes. I’ve structurally enhanced the jaw and I will discuss that with @CaryF300 offline.
FYI, I have the blue and magenta bones printed for the left side, I think, and I’ll be bringing them to the Space tomorrow.

Skull printed well, but I have to tweak my support settings and have the slicer check for thin walls.

I need a decision please about whether y’all want to use hands.
I have been working on a hand model. I’m articulating the fingers around the pipe that could enclose the frame. It isn’t done yet, but I wanted to see if there’s enough interest for me to continue. We already have several proven models for various joints plus a skull so @rlisbona - you and the team please decide if I need to finish the hand.
Not to mention … my brain is swimming trying to figure out where to split it so it can be printed.
It’s pretty big once the arm bones are included but it will fit in Bubba.
