i3 in a Box - Joe's RepRap

I designed this printer to get a very rigid and easy boxable construction without any too complicated mechanics.

I used many parts of my old Prusa i3 - so basically, it's an i3 with a 2020 aluminium frame inspired by Haeckel, and most of the Prusa i3 x or y-Axis parts will fit. This one uses 8mm trapezoid threaded rods with 17mm nuts, feel free to build it with any other i3 x-ends.

The X-carriage is a modified version of clefranc's Universal X-Carriage: http://www.thingiverse.com/thing:97719
Just added a small piece to hit the endstop switch.

I like ffleurey's direct drive extruder: http://www.thingiverse.com/thing:147705 download it there or use any Prusa i3 extruder you like, or use a bowden setup as shown in the second picture.

For endstops, I'm using some like these, or just be creative:

Print space (depending on extruder design) is 200x200x210mm, with enough clearance on x-axis to add a dual extruder. Anyway, dimensions are easy to vary by the lenght of the aluminium extrusions.

*Update 22 April '15: Some minor changes...

• clearance to insert TR8 Nuts
• made belt guides a bit wider
• made tensioners wider
• 3-way-connector is now more printable and has more clearance

*Update 19 Aug '15: Changed length of the extrusions. 430mm just wasn't enough for Y-direction!

*Update 09 Okt '15: Uploaded a new version of the bearing clips and a belt holder with tree holes for the printbed. Seems like the drawing I referred to was a quite old one, these should fit much better.

*Update 25 Okt '15: Added/modified the x-carriage, new picture
