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

thingiverse

I designed this filament guide as an anchor point for a 4mm PTFE tube running from a filament drybox, clamping directly to the center of the top frame of my Prusa i3 MK2S. V2 adds a riser for the PTFE port, preventing it from hitting the extruder at maximum height. This isn't an issue for most prints, but it becomes problematic when raising your Z to the top for maintenance tasks (don't ask me how I know). There are three versions of this file: M10 - This one features a threaded hole accepting a PC4-M10 Male Straight Pneumatic Tube Push Connector. I also included a version with custom supports because it's challenging to add supports in most programs without adding them to the M10 threads. 4mm Hole - This one has a 4mm hole for inserting your PTFE tube or using as a regular filament guide. Solid - I'm not sure why anyone would want this, but you could theoretically print and drill your own filament holes if desired.
