This is a parametric pirate hook I made for my son's birthday party. It fits the paw of a 4-5 year old very well.

It consists of three prints, the cup for around the hand, the hook, and then the grip and joining piece. My son really likes it, although the hook is a little primitive.

I've included the SCAD. The cup file is parametric, and while not greatly laid out, it should be easy enough to scale up or down. Its also relatively tall, and could easily be shortened by a centimeter or two. The other files are not parametric, because I was in a hurry, but they should be easy enough to adjust.


Simply print all three parts. Then dry fit the grip, hook and joining bracket. Then make sure the hook passes through the cup hole. Finally use glue to assemble the whole thing more permanently.

There is nothing about your model that could be considered 'parametric' !
The more proper term would be 'solid model'.

I made this for my daughter, and she loved it. I didn't have to uses glue or anything to get it to stay. I actually had to trip the "T" down a bit to get it to fit inside the little plug. Hook fit just fine.

Although my dear mother made the little comment of 'why don't you just buy one at the dollar store', we all already know of the implications simple things like this bring to the 3D printing community. I can personally imagine every cheap plastic toy, dodad, prop, and misculanious organization tool in the dollar store to be a great start for 3D printing.

Anyway, this little prop is great, although you said it needs improvement I think this is very well designed considering the limitations of current 3D printing. Not to mention it's a simple costume prop, not an actual prosthetic. The only thing I'd ask you to consider doing is to find a way to a
ssemble the prop without the use of glue, like snaps maybe?

But yah, this is very well designed and constructed.
Also, tell your son to have a Swash-Buckling Halloween.

I see the real power in, the ability to customize designs to better meet your own desires. Change the color, change the size etc.

I still need to better adjust my printer before I can print accurately enough to get clips and the like working for me consistently, but thats definitely a long term goal for me.

First off - AWESOME!!!!

Second - there are lots of other ways to avoid the use of glue besides just snaps. If you put a cylindrical hole in the hook, another in the handle, and two in the connector, you could use a small piece of filament as pegs inside.

That print quality looks pretty good. If you're looking to adjus
t your printer, there's a series on the MakerBot blog about getting printed results. Another thing you could do is use Print-O-Matic with the latest version of ReplicatorG or ProfileMaker on my site. http://makerblock.com/profilemaker/http://makerblock.com/profilem...

ARR, matey! Nice work!
