Modified Kossel Parts


Frame Brackets:
You will need 6 brackets for the base and 3 for the top. Place the M3 screws and bolts in place before you slide in the open beam. These brackets have a 0.5mm 'breathing' space between the open beam and the part itself on all sides.

Power Supply Brackets:
The shorter brackets are for the front, while the longer ones are to be set diagonally

Heat Bed Brackets:
It may not be obvious, but 2 of them are shorter than the other 2. The longer ones go in the front, while the shorter ones go in the back.

Arduino/Ramps Bracket:
This will require you to remove 2 screws to the side of your PS. One of the screws taps into a internal heat sink. Be very careful because putting back the screw may be difficult if the heat sink is dislodged. You may need to stick a non conducting probe in to hold the sink in place. Make sure you unplug the PS and wait for the capacitors to be completely discharged before handling the PS.

LCD Bracket:
This is for the reprap discount LCD panel. no screws needed! just slide it into the beam. Do not put this on the bottom most beam because it is slightly protruded and will hit the floor. It's meant to be attached on the same beam as the heat bed's mounts.

Motor Plate:
Get some M3x8 screws and mount the nema 17 to this plate. Then mount this plate to the brackets.

How about a 20x20 version to the ones of us that doesnt have openbeam at their countries? In another side note, can you state the length and quantities of the openbeans cuts?

I love your mods! I was planning on building the Kossel as my first 3D Printer as I already have almost everything I need, but I like the changes you've made. Do you have any idea how much I might expect to pay to print your parts at my local hackerspace (Metrix in Seattle)? The closest answer I've gotten so far is "it depends".

Do you have scad files for these? I'd like to modify them for 2020 or maybe 2040. Thanks

Sorry I don't.. haven't learned SCAD yet. :)
