FilaSpoolCase

::UPDATE::
Added version Z that does not require a spool core (typically comes with Geeetech / Creality printers).

::UPDATE::
Added an adaptor for M6 pushfits - for use with ptfe tube | PC4-M6 for 4mm OD tubing / 1.75mm filament | PC6-M6 for 6mm OD tubing / 3mm filament
Note: I find the unthreaded one works better

::UPDATE::
Now snap-able and one size fits all! (fits either 1.75 or 3mm filament)
Simplified silica packet compartment and core, and thinned down the base for easier and quicker printing

The snap-fit pegs are 4mm in diameter

Part A comes in 3 different snap-fit hole sizes - the number at the end of the file name corresponds to offset radius:

filaspoolcase-X-A-0.05.stl = 0.05mm
filaspoolcase-X-A-0.1.stl = 0.1mm
filaspoolcase-X-A-0.2.stl = 0.2mm

actual hole size = 4mm + 2 x offset radius

Use this fit test to determine which one will work best for you: https://www.thingiverse.com/thing:3513594

• So if your peg fits, let's say, hole size 4.1 (diameter), then you'd need to print part A size 0.05 (radius)

  I used an Anycubic Chiron (400x400x450)

  Suggestion: tape the seam up with masking tape
