Quick n' Easy No-Frills Spool Holder

This is a quick print (1 sheet) mega-easy no-frills spoolholder for top-mounted 3D printer applications.  For a spool of filament that rides on (4) bearings and dispenses filament with the force of the extruder motor.

This design was inspired mainly when I needed a spoolholder specifically for my Prusa Enclosure.  After installing an LED setup on my MK4, I realized there was no longer room to mount a filament spool inside, with a PTFE tube, etc.  So it was decided to simply mount the spool outside.  

A printed bearing option is version is available here using the BEST version of a printed bearing that I found here on PrusaPrints:

Lots of credit to maker A5 for designing and testing.  

I was inspired to improve Slacker's design for the Enclosure version here:

WORDS:  As many of you already know, but those that don't--printed bearings do actually work and spin.  In a world where standard stainless 608 ball bearings are a click and 10 bucks away, it is an easy decision if faced with which one to use.  Printed bearings are more of a “stop-gap” while waiting for metal bearings.  The fiction and weight of 1 kg of filament combined with cardboard edges make for herky-jerky (and a little noisy) spool dispensing.  They work slightly better with molded plastic spools. 

YOU WILL NEED:

If your are printing a version for the 608 bearings, you will need (4) of those.  They are available almost everywhere on Alibaba and Amazon, McMaster-Carr, Digi-Key, etc.  

If you would like to use printed bearings they are available here:

For Enclosure version (2) M3x12 bolts with (2) M3n nuts are needed to attach to the center opening in the Enclosure.  

PRINTING:  

As the title specifies this is no-frills.  Flat parts that fit together with slots.  PLA with DRAFT layer height on an MK4 will work just fine, I do recommend randomizing the seams for the plastic pins.  

Use a touch of tree support in the bolt head counterbores on the enclosure design.
