For those 3DS Cube 3 owners: This submission is to replace the stock 3DS cartridges with a bulk filament hub for improved performance and convenience. The core option is a remote filament solution. Everything in a stock cartridge will convert to this solution.
NOTE: This "solution" provides a push-to-connect fitting with either an M5 or M6 thread to connect to a feeder tube of your making. There are 4mm tubing and hot-end solutions and some have had luck with 3mm tubing. With another adapter, even the stock tubing can be put back into service. Although that is where 90% of filament feed problems spawn from.
These are only useful for Cube 3 printers, so that is the format of the print files.
The included STL is an accessory template in case you want to make your own spool holder.
The included despoolers are for the stock 3DS spool.
Feel free to make your own accessory with the included template file in STL format.
Attaching an accessory to the clamp requires 2 each M5 cap screws (common bicycle hardware).
The screw length can be from 8-12mm long. Other mounting options can be imagined.

Optimized and fixed for your protection :)
Files support Left side PLA only on your Cube3 printer using the stock Cubify application v4.03.
Print only one clamp, M5 or M6, depending on your available fittings
This is fairly straight forwards but just in case.
Key takeaway: The filament should feed without restriction through the hub. Careful attention to the images below will help you glean the operations. Feel free for clarification in comments as needed.
Supports are built in. If it looks like it shouldn't be attached, it probably shouldn't be.
Chip holders are little springs. Do not use brittle material. They print in pairs for best results.
Some cleanup in the pocket may be required. Chips should recess slightly.
Depending on your 1st layer gap, you may need to clean up a few edges where there are holes.
The through hole for filament is 2-2.2mm, the hole at the feeder tube is 2.8-3mm.
Reaming with a hex wrench will make short work of ensuring proper clearances.
Threaded holes are ready to use; however, a poor-man's tap is recommended if the threads feel too tight.

This project had a reluctant start. I still believe in modifying stock cartridges because they are convenient for travel. The group effort from good people at the Print3DForum had nailed this effort with a very simple solution called the KISS Carts.
Another effort started to install a permanent feeder on the Cube 3. Eventually, it lead to just driving the filament with a file so now a dual effort has come to light. This is one of them.
Please do not hate me for not releasing the STL files. In order to support something this simple is to define a complex design. I am willing to support this project but I need to know what was printed before a conversation becomes meaningful. This process lets the conversation commence much sooner.
And for those who want their own, I welcome anyone to copy and change the design. If you can extract an STL from the .cube3 files, go for it. I certainly am not trying to stifle anyone else's efforts.
