This video ended up being a little longer then I expected, so I'm going to re-upload just the moulding tutorial clips on Tuesday so that people have an easy reference to refer back to

Very interesting, as usual. I have used your recipe (approximately) for 150g Antweight wheels for some time, I've never tried overmoulding. I think it's interesting that the separately moulded tyres are usually made under-sized - at least, I do mine about 25% smaller and stretch them on to the wheels. But when you overmould them they will be 100% size, so are automatically looser, and I think this explains the failure mode you observed.

I have a question: What type of code do you use? (java, python, etc.) Thanks!

You can get hex shaped hubs that attach to your motors and would better fit your wheels over the round ones you have in the start of the video at least. And instead of the grove in the center, or its evolution with the holes, that is in the middle of the printed wheel, have you considered making a set of tabs that the silicon has to get into and the inside of the wheel part of the tab would have a larger head to anchor the silicon wheel, or maybe a L shape, some way where it has to do some crazy stuff to get loose. And for your molds, you might consider adding a loop for your fingers with a flat end so the mold can stand. put a finger loop on both parts so you have something to grip and can just pull them apart. Or if you have a quick clamp that you can convert to a spreader, make your loops able to slide onto the spreader part of your clamp, then your using mechanical means of separating things Edit: the thing im noticing is, when you have rotation and lateral movement, is when you are getting the tire off the wheels, you could see it both rolling up on itself in the direction of the rotation, but you could also see as it started to move laterally that it was pealing up sideways

My god has it been a week since your last video already?

great work as usual, i do like to see your thought process and design evolution. just a thought, longer pegs/locking lugs for the mold for tool-less release when pressing on a surface

Do you ever add any cornstarch? (people call silicone and cornstarch "oogoo")

I 3d print my tires in tpu and they're like tank treats with little notches and i print them smaller and stretch then over the wheel, haven't had issues

Would locating pins on 'wings' of the 3 part mould so it stays concentric help?

I have tried to make those tyres a few times with the old moulds you uploaded (printed in ABS), and each time, I failed. My most recent attempt was ALMOST a success, but when trying to fit the tyre onto the wheel, it split apart. I refuse to give up of course, so it's just been a series of trial and error. It is good to gain further knowledge of this technique. Using tiny amounts of paint and glycerine, leaving it to cure for the required time length, it's good to learn all those things. Are there any particular brands of silicon you would recommend? Maybe I could be using the wrong type, as I only followed the "100% silicon" guideline from your old video. Is there also a limit on how many times you can use the same single mould? Can it be cleaned easily? I recently saw Chris had used an ABS mould for Lumberjack's wheels, with success, but that could be just because it was fresh from printing. Sorry for the avalanche of questions. I'm just so eager to learn!

Instead of clippers you could use screws to fasten the three-part mould together.

Have you ever made 1/24 digital car tires in if you did would you sell any
