You could print the outside part out of a hard material like PETG and the inside out something like TPU so you could squeeze the TPU to fit inside the outer part.
Also on the second barrel you can use the OFFSET FACE on the ridges that poke thru to add a little gap for tolerance. Like 0.5mm
Hi,
Here, an other way to realize the cask.
1 - sketch on front view
2 - Tool : Revolve 36° to do a plank and fillet it
3 - Tool : Circular Pattern (x10 = 360°)
Good. You are getting the idea how to “Extrude” a cut out of an object with a sketch. You can use multiple sketches from different angles. Adding “Planes” can come in handy for this and can easily be moved where you need them for a surface to sketch on. You can only sketch on flat surfaces. You can “Project” a sketch onto a non-flat surface. Like text to personalize it for your son.
I went there too. But in my mind I made a “spoke-like” sketch below a revolved barrel shape and extruded the spokes up through the barrel to cut it into staves. (pre-circular pattern tool thinking).
You are pretty close to it. Both methods will come in handy here. Cut the thing in half vertically in your mind and sketch that. I see four possibly five separate revolved items in this pic.
Not practical for multi-color printing, but this is what I see the way it was manufactured. 5 revolve operations.
Again thank you it makes so much sense to do it it like that
