The K1-Rap is a derivative of Dkennel's Pocket Printer. I loved the design and idea of the Pocket Printer but was unable to get the "slides" working correctly. Since I had 8mm smooth rods and lm8uu bearings on my Prusa, I decided to cannibalize it and start a new design based on the Pocket Printers basic shape.
Check out: www.entropyprojects.blogspot.com for the full details.
I'll update this as I change things.
Due to popular demand, I changed the name to include the build number. Hopefully this clears things up.
Full instructions and BOM to come once I stop making changes. STL's are in the Zip Folder.
You'll also need the pocket printer's xymotor mount, RAMPS holder (if needed), and Prusa's lm8uu Y bearing holder.
2 - Zmount
6 - barendbracket
1- Zslide 2L
1- Zslide 2R
1-hotendmount (this may not work for everyone, if you need a different hole spacing let me know)
Z Cantilever = 180mm 2060
Z Vertical = 300mm 2060
Y = 425mm 2060 (Mine currently is shorter than this because I miscalculated. This is what it should be at least. A little more wouldn't hurt anything)
X = 2x 350mm 2020
"Legs" = 1x 350mm 2020 and 1x 150mm 2020
Same sizes as axes, 2 per axis.
11 or 12 lm8uu linear bearings
2x 220mm threaded rod. I use 5/16 since I'm in the US, but 8mm will work too.
Plus whatever Z couplers you prefer.
3 Nema 17 steppers
1 Nema 14 stepper (X axis)
Belts/pulleys/idlers are your personal preference. (I use T5, right off of my Prusa)
