Very attractive artichoke model for use as a standalone piece or can be mounted on a rod or other structure.

I wanted this for the tops of an arch I bought ages ago from Wilko when they were still in business. The arch turned out to be far too big for our garden, and I decided to leave out some of the rounded arch sections at the top and convert it into a Gothic Arch using a printed adaptor which I've designed and included in this model. The adaptor is for that specific arch so may be of little use to anyone else, but it's here just in case! 

Having designed the adaptor, I wanted something on top to improve the look. The artichoke seemed in keeping with the design so that ended up as the decorative feature, but you can use it as a standalone model, or mount it on other structures.

You can scale this as you wish, but remember that the mounting peg hole in the bottom will be scaled along with it. To make it more of a globe, just scale the Z separately from the XY. This model prints about 65mm wide by 80mm high if it's not scaled.

I used 25% density zigzag for the support which worked out fine and removed nicely (see pics) leaving a decent bottom.

The adaptor should be printed with the small hole facing the printbed, no support needed. I used a couple of lines of brim for adhesion. They are arbitrarily labelled L and R, you'll need one of each if you want the male-female ends of the arch tubes to point in the same direction, otherwise it doesn't matter which one you use, they're just mirrored.

The connecting peg is printed with either end on the printbed, again no support and just a couple of brim lines for adhesion. Strangely, even though the holes in the artichoke and adaptor are the same size and printed in the same orientation with the same material on the same printer with the same settings, I found the peg was tighter in the artichoke than in the adaptor, so that just needed a few strokes of a deburring tool to shave it so it's not too tight in the artichoke. If you scale the peg with the same %'s as the artichoke then it should still fit, or just design your own peg to fit the final hole, it's just a peg :o) I nearly whittled one out of wood but why do that when you have a 3D printer!

Before you ask, yes I still need to print another artichoke for the other adaptor!

Please Like this model if you find it useful.
