June 13, 2015: I got the GEEETech Prusa i3a a few months ago as a DIY kit. It was a bit challenging because the instructions were incomplete to say the least. I think I took the Z axis apart at least 3 times to finally get it right. Let me also say that 3d printing is not for everyone. Unless you spend a lot of money to purchase one already assembled, expect to take some time to learn how to set it up, calibrate and use it. There are very few 3d printers that just work out of the box, especially in the sub $700 range. As a final bit of advice, check out as many reviews, and user builds that you can. It may keep you from purchasing a lemon.

It is a bare bones printer, but it is quite a value. Mine was under $360 with free shipping and it took exactly one week to arrive from China. Not too bad. The only parts that were missing were 2-2.5mm nuts. This wasn't a show stopper, as I have a lot of miscellaneous screws and nut from all of my salvaging of parts. Also, their email tech support was good and pretty fast too. I would ask a question one day, get the answer the next. Additionally, they have a forum with a lot great information in it as well (see it here). There are lots of good pictures too, which helped when the assembly instructions were lacking. I was expecting some challenges, but my philosophy is that if you can build it, you can fix it. It also make you less afraid to make modifications. 

If you are interested, here is the printer on GEEETech's website. The prices seem to change weekly, so your milage may vary, but as of today the Acrylic Geeetech I3 pro B 3D Printer kit is only $296; however, I don't think that includes shipping. My model was the I3a... 

As always, I ended up doing a lot of research on the internet and found a couple of YouTube channels that were extremely helpful.

Thomas Sanladerer - Tom's Channel - Everything from How To's to honest reviews... 

ZennmasterM - ZennmasterM's Channel - Lots of really great information. This is how I figured out the auto bed leveling!

I have added a spool holder, auto bed leveling, and a cooling fan (see pictures below). I have calibrated it about as best as I can. The extruder was really way off, but the rest of the settings we spot on. Thomas SanLaderer's extruder calibration video explains everything.

I am contemplating getting an aluminum bed. I am thinking that it may add some regidity and may improve my print quality. Additionally, I could then use an inductive sensor for auto bed leveling.  Another possible upgrade is to replace the M8 threaded rod with M8 lead screw. 

If you have any questions about this project, email me.

Spool holder

Here is the spool assembly. I glued a filament guide as an after thought because the filament was rubbing on the base of the spool holder. The camera is for my Octopi server running on a Raspberry Pi
