-Added a new version fixing overhang.
-Tested with extruder. Feeds clean. Although I really recommend canola.
Edit: Make sure to print this in the orientation it appears in the picture. Printing upside down will not print correctly due to the cavity being modeled a certain way. To be frank, it's a blessing it works as it does, it's basically a science that I've learned from other models to create and there's a lot of calculating that goes into its sizing. I'll definitely make the threading entry cleaner, and perhaps someday make a revamp. If there's any tweaking I can do to the cavity to make it easier to print I surely will.
This is a completely original make of a bowden 6-1 splitter. I'm now making my previous release defunct. I'll have the files up for a while but it'll soon be completely done.
Should work, may be some clicking when it goes in but nothing that will halt an extruder if it's printed correctly.
A little canola doesn't hurt.
This is version .5 alpha. RC1.
If anyone had trouble with the last one, my apologies, didn't think it would be this advanced of a task. Definitely learned along side.
Print this with no supports, if it seems like it needs them, there's something wrong with your printer.
Overview and Background
6 in 1 bowden
This is a simple print to allow 6 to 1 bowden printing. This wont mix colors but you can select them from each roll. Should just require some retraction editing and install.
To be clear, this will allow you to print multicolor models assuming you configure the settings correctly and install a cnc v3 shield to a RAMPS style setup with the right wires, jumpers, stepper drivers, cables, and power.
From page: "This method [cnc v3 shield] can be used to add up to 4 extra motors while still leaving 4 IO pins, fan extender, and LCD functional. There is no need to go buy an expensive board meant for a kraken because we only use 1 heater."
If you scroll down this wiki you will find the correct setup instructions. "RAMPS using CNC Shield" Good luck.
You will need a total of six extruders, you should already have at least one so get to printing.
2020 multi extrusion extruder:
Compact bowden extruder (what the first one is based off of). The video in this thing page has the correct instructions for calibrating e-steps. Even if you don't utilize the extruder, watch the video.
Another good one for this:
example: http://amzn.to/2CyY4G0 I have two of these. They work amazing, you may want to order your own springs. Smooth prints. Reprap Champion seem constantly sold out so don't be afraid of these ones. Metal is better but sometimes you cant fit 6 of them.
really nice one: http://amzn.to/2EUWHqp
Lesson Plan and Activity
You will need to print this case in order to house the cnc v3 shield if you're to use the shield as this model was intended to use.
Doesn't have to be this case but you'll need a way to mount it and I've designed or remixed one for everybody.
Spool holder for dollar broom or various things re-purposed as an axle fits over 6 spools:
Install by cutting the correct lengths and connecting them to each extruder.
I will add more to this once I've done the full install.
