Twist-Lock Spool Holder v3.6

Highlights

Since my first few versions weren't perfect, I present "v3.6" of my spool holder. A much more refined version that offers a smoother workflow for changing out spools. This comes after dogfooding a development version of a previously released spool holder and suffering through the usability issues on my own printer. Includes ECC1 tuned profiles for Polymaker HT-PLA and Polymaker ASA.  

New Features

• Internal finger grip for twisting the holder.

• Self-centering 1/4-turn twist-lock interface for much easier alignment in tight/low-visibility situations.

• PTFE "lube tube" channel actually holds the tube in place.

• Minimized direct spool contact points to reduce spool resistance, even without PTFE.

• You may adjust the holder length by reprinting the mount. +0, +1, and +2mm versions included. +0 will work with a 5mm panel spacer. +1 and 2mm are best used with a 7.5mm+ panel spacer.

Notes

• Avoid regular PLA. It may survive the heat for many people, but creeping over time could be an issue.

• Do print in PETG, ABS, ASA, or similar materials.

• Should be printed with at least 4 walls due to the layer line orientation and given stresses under use, especially for more brittle materials like PLA variants.

• Tight tolerances are sensitive to elephant's foot, especially where brims are used.

• PTFE "lube tube" is optional. The spool holder already offers relatively low resistance.

• Be gentle with it. When the holder fits well in the mount, the spool holder may be used indefinitely without feeling fragile. If you get aggressive with it, it'll probably break unless you print the holder with 6+ walls.

• If the fit is a bit too tight, you might do a "break-in" by inserting and turning the holder in the mount repeatedly until it loosens up.

• You may also use a little petroleum jelly to lube it up. 

• If all else fails, try XY hole compensation in your slicer by adjusting the mount hole size slightly. Then, reprint the mount part.
