Awesome model by ErikJDurwoodII on Thingiverse!
I printed these guys small for a quick test print with a new extrusion profile I was trying out, but it’d be worth spending a couple hours to print them huge.

As many people may know by now, Thingiverse is an awesome platform for people to upload 3D model files that represent real, physical objects that can be created from the source files provided. This means that as the consumer-use 3D printing technology inevitably infiltrates everyones’ homes, everyone will have a place to go to download free objects and print them out right at home. Talk about manufacturing on demand.
Last month some people over at the MakerBot Workshop uploaded some very interesting 3D printable toy figures and playsets.
They first released the MakerBot Damsel and the MakerBot Astronaut; two designs that set some of the system standards for an open-source line of toy action figures.

Simple, stylized, and partially articulated, these figures would serve as a platform for other Thingiverse users to create and upload more toy figures that played nicely with the originals.
MakerBot Workshop also released 2 HUGE playsets for these figures – a Castle and a Rocket. These things are awesome.
I wanted to make some additional figures, so I created a Knight - the Damsels & their castles seemed vulnerable.

I wanted to do a Wizard next, but after I spent some time modeling the hat I decided to also make a Witch using the Wizard’s hat and the Damsel’s body.

Once the beard was finished, I made some robes and voila – the Wizard.
And of course the whole point of the interchangeable system… customization!
See MakerBot’s post on these playsets here

These models are all printed in ABS (common injection molding material – same as the material LEGO uses), but I also have a spool of PLA (plant-based, often made in USA) that I’ve been experimenting with.
I did not design any of these, they are all user contributions from the popular 3D content site Thingiverse

Depending on which manufacturer you order your plastic from and how much you order, your plastic won’t always come on a spool. Most sites will indicate if the product is spooled or not, so make sure to check so you know what to expect.
If you do order plastic that is not spooled, it can be a real pain to work with. You have to constantly keep an eye on it and help feed it in properly so your extruder motor can handle it and allow it to properly feed through as you run your print. To solve this issue, Thingiverse user randyy made a filament holder with files included for clips that the filament feeds through as it enters the machine. This allows for a seamless, smooth print that you don’t have to constantly watch and intervene.
The cool thing about collaborative sites like Thingiverse is that people see designs like this and help to improve them. RotoScan made several modifications to the original design and released this heavy duty filament holder & guide that I printed out for my filament;

This whistle works! Since I don’t currently have 2 extruders I don’t have the option of using support material (this would allow large overhangs and printing objects inside of objects). That means the “ball” inside this whistle doesn’t float – it is attached to one of the walls but protrudes into the cavity enough to allow for a perfect, loud whistle every time;

Check out this bracelet design by Thingiverse user emmett. It is printed with thin walls which allows it to stretch and expand to fit around your hand as you put it onto your wrist.

There are a lot of printable upgrades for your personal 3D printer available on Thingiverse such as this one to remove dust on the plastic filament as it enters the extruder;

I accidentally broke a friend’s bottle opener the other week, so I printed a replacement from a file uploaded to Thingiverse

Here’s a minimal, straightforward toilet paper holder – I added some words wrapped around it for fun and mounted it in our bathroom

It’s a great time to get into the world of 3D printing on the hobbyist level. There are tons of companies offering relatively inexpensive kits with all the parts you’d need to build a fully functional FDM style 3D printer. These are the type that operate by heating a thermoplastic (generally either ABS or PLA right now) and then extruding it through a nozzle onto a build platform. As it does this, each axis is moving according to a 3D CAD file. By controlling the movement of the nozzle/ bed and simultaneously controlling the plastic coming out of the extruder, these machines will build a three dimensional plastic part that is accurate to the 3D file inputted into the software.
I hope I didn’t lose too many people on that explanation. For a growing number of people, that is pretty basic information about these printers. However, it is still not fully adapted by the masses, which is why it is currently in the hobbyist phase. These 3D printer kits are getting cheaper and more reliable each day. There are huge communities of smart, helpful people that are testing, troubleshooting, and contributing knowledge to these projects.
Many of the kits are open source, which allows knowledge to be shared amongst anyone interested. Open source basically means that the “source” (original backend work to create final product) is openly revealed and provided to anyone who wants it, free of charge. Open source is common in software development and has led to awesome, well-rounded products due to the immense knowledge being contributed and reviewed by anyone interested.
Last October I ordered a 3D printer kit from one of the better known personal 3D printer kit companies, Makerbot Industries. Their newest model is called the Thing-O-Matic and I got the kit of parts to build it for about $1200 USD directly from their online store.
Although there are several companies and models being offered from different people, Makerbot was relatively inexpensive, has a very user-friendly appeal and therefore attracts a large community for support/troubleshooting help, and they’re doing a good job in the current hobbyist climate that these kits are in. They’re also behind the immensely helpful and popular site Thingiverse, which offers free 3D models (user-submitted) free to download and print at will.
Other good 3D printer kits are Ultimaker (known to be a faster machine) and MakerGear (great site for kits and parts/ extruders/ plastic/ etc.). These are just 2 other sites I was considering when making my purchase, but there are tons of companies with offerings. Check out this helpful post on the Fabbaloo blog for a list of some.
The grandfather of all these extrusion 3D printer kits is the Rep Rap Project. What an awesome initiative and project! There is a huge community constantly developing add-ons, updates, and improvements and helping to make personal-use 3D printing widely adapted and able to improve our quality of life. Imagine never having to go out to the store to buy simple things – just download or create them in 3D and click print.
I’m planning on starting my first RepRap build soon, and if anyone else is interested you should check out this awesome visual guide to the Prusa Mendel build. Very informative and detailed, I’ll definitely be referencing this as I build.
