Bronto Bracket - Prusa MK2s / MK3 Filament Guide (V2) by captfoss

I designed this filament guide to serve as an anchor point for a 4mm PTFE tube running from a filament drybox to clamp directly to the center of the top of the frame of my Prusa i3 MK2S.
V2 adds a riser for the PTFE port, so it won't hit the extruder at maximum height. That isn't really an issue for 99% of prints, but it tends to be if you raise your Z to the top for maintenance tasks (don't ask me how I know).
There are three versions of the file:
M10 - This one has a threaded hole to accept a PC4-M10 Male Straight Pneumatic PEFE Tube Push Connector
Also included a version with custom supports because it's difficult to add supports with most programs that won't add supports to the M10 threads.
4mm Hole - This one just has a 4mm hole you can use to shove your PTFE tube into, or you could use this one as a normal filament guide
Solid - Not sure why anyone would want this, but you could theoretically print it and drill your own filament holes in it should you desire to do so
