K1-Rap Printer

thingiverse

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. Edit: Due to popular demand, I changed the name to include the build number. Hopefully this clears things up. Instructions 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. Parts needed: 2 - Zmount 6 - barendbracket 1- Zslide 2L 1- Zslide 2R 1- xmotor 1- xidler 1- yendbracket 1-yendbracket2 2-ySlide 1-hotendmount (this may not work for everyone, if you need a different hole spacing let me know) 1-beltbracket 3-endstop Vitamins: Aluminum Extrusions: 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 Smooth Bars: 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)
