Up for sale is my mini kossel.  It is a well built printer that has very little run time on it - in fact I haven't run it at all myself! Bought it from mdrvb6 to play with Deltas but never got the time. he sourced all parts himself.

Details:
1515 misumi aluminum extrusions, 240mm and 600mm (standard sizes), so approximate print area is 170mm diameter by 220 mm height.
All printed parts printed in ABS by me on my solidoodle out of black or blue ABS (except extruder gear, which is nylon)
No Hotend, but I can include one a brand new E3Dv6 for $50
Motherboard is a RAMPS 1.4 with DRV8825 drivers for 1/32 microstepping.  All wires are labeled with a label maker at the board.
GT2 belts, 20 tooth pulleys, NEMA17 1.8 degree motors
Heated bed is a very nice silicone pad, 240 watts, not a cheap resistor based board like other kits.  It has an aluminum spreader pad, heater is held on my its own sticky pad and then insulated with cardboard held in place with kapton.  Then I counter sunk the attachment screws and installed the bed on springs to avoid damage if you crash the head.  It also has a custom cut glass bed over kapton.  Really a very nice heated bed!
Extruder is a geared Wade extruder, so it has a lot more torque than other kits that only use a drive gear direct on the motor.  The gear is nylon, so it runs much quieter than other ABS of PLA gears.  All springs and bearings are in excellent condition and came from McMaster, not a cheap Chinese supplier.  There is also a custom filament roll holder on the top so it feeds directly into the extruder.
Top and bottom have thin woods panels to keep everything tidy.
Also includes 3x FSR sensors.  I never really liked these so I took them off, but maybe you will have better luck.  You would have to go back to an unheated bed (not recommended) or use one of the groove mount kits to mount these in the print head.  This is really a mod for a serious tinkerer.  Good luck.
Everything connects fine and I have confirmed that all heaters and thermistors work.
The probe has not been installed since I never got around to it.  I will include the endstop but I don't have the various springs, etc.
NEEDS: a PSU, Hotend

This is a good printer, I just don't have time for it. Asking price is $150 shipped in the US.
