Please ignore the potato quality photos.  I have my bracket and W_Shade's original remixed bracket side by side.

 

The big difference is a fully enclosed bracket for your spool arm.  This remix means if the pin were to vibrate out, the entire spool and spool arm will stay mounted above the gantry instead of falling on your build plate.

 

I first printed W_Shade's bracket, but as soon as I mounted it, I felt veeeery uneasy about how the self-tapped screw was the only thing stopping the arm from falling down towards the build plate, especially as it's not a particularly tight fit.

 

I noticed that the spool arm once mounted was actually not as deep as the bracket by 1cm. Along with this, it had an open face that didn't need to be.  I added a wall with a outer sloped top, which reduces the movement inside the bracket a lot.

 

It's still not a snug fit and it can wobble, however there's no longer a risk of the spool holder leaning further than a couple of degrees, where previously it could potentially fall an entire 90 degrees.

 

I've included my Blender project file if anyone wants to make this a snug fit - I've used Blender for a total of 1.5hrs with 0 instructions so suffice to say I barely made it happen.

 

Both STL and my Prusa projects attatched.

 

I printed 0.2mm layer height on an 0.6mm nozzle with Overture PETG Red at 250c and bed temp of 70c.

 

 

Finally, a HUGE thank you to @MichaelNicola_459990 and @W_Shade for designing and allowing remix culture on these files as I would literally not be able to have created this final version without your hard work.  Go chuck these fellas a like if you can.
