I needed a 45 RPM record adapter so I created a 'volcano' style adapter. Included is the original 123d design file so you may make whatever changes you feel necessary.
I started into 3d printing just out of the interest in the technology and because it's the closest thing we have to the Star Trek Replicator! When I first got the printer I was looking for things to print that others have designed but now that I have it I find I design and print items I want or need. There are many things I have not published but the items I have here are either interesting and/or useful or are some of my first attempts at designing a printable item.
If there is something you want designed reach out to me and ask. I don't know if I can do it but I might give it a go!
