I've been using the Ultimaker 2+ for several years now and love the printer! I started out with Autodesk's 123D Design and loved it due to it's simplicity and mainly because I didn't have any real CAD experience and was a noob. Autodesk has since dropped this product and you have to use Fusion 360 which is a better CAD product, but I grew up on 123D Design and don't care for Fusion. I've used the Ultimaker 2+ to build gear boxes, gears, axles, support arms, enclosure boxes, stepper motor mounts, etc. Some of the parts I used to print took 36 hours and the Ultimaker with its heated bed did a awesome job! But you have to make sure that you put the printer on a UPS just in case you loose power (which happens where I live). Ultimaker with Cura (slicer app) and you can't go wrong.
