Similar style to the stock design, but sturdier. Most suitable for revision 2 or above printers with the new filament inlet design.

Voron style spool holder with PTFE tube to ensure smooth operation.

I didn't went with a design that protrudes to the left, because that will create an extra bend in the filament path, and it won't save much space as you still need one extra spool thickness worth of space on the left to load and unload the spool. I do prefer the stock design, because the filament feeds in straight, which is especially important when printing coextruded filaments (dual or tri color that sort of stuff).

It's flimsy because it was not redesigned for the second revision printers, so it is pushed too far back to support the old filament inlet design. The image shown is 8mm thick, the STLs are updated to be 12mm thick for more rigidity, it's still a bit flimsy, but there's not much I can do.

It kinda looks ugly and weird, but for a reason, it is to optimize print orientation and avoid post processing and assembly by printing in one piece. You don't need extra hardware to install this. You do need a piece of PTFE tubing.

Insert the PTFE tube from the rear. You might need some grip and patience for this. Hold the tube as close to the hole and do it slowly bit by bit to prevent the PTFE tube bending, although it's fine if it is bent. The grooves will hold it in place.

There is a matching hole on the front bar, this will be challenging to insert. Therefore, cut your PTFE tube leaving 2~5mm from flush. Then, press the protruding tube against a table or a hard surface, and it will go into the hole and hold in place firmly.
