These Saddles (regular and short versions) replace the rollers in @GunplaMark's The Ultimate Cereal Container Filament Drybox - Official Remix to work with my Auto-Rewinder for Ultimate Filament Drybox to eliminate problems with tangled filament due to MMU ejection of filament with each filament change - without requiring an MMU buffer!
The following render shows the normal Saddle - the Short Saddle is 7mm (~0.28") shorter to support larger 1kg filament spools:

The following photo shows the new Saddle in use:

To allow modifications, I have provided a STEP (.stp) file.
A PrusaSlicer 3MF file has been provided for PETG.
A G-code file has been provided for the Original Prusa MK4 for PETG.
The Saddle seen in the photos was printed with Prusament Carmine Red Transparent PETG with a 0.4mm nozzle at 0.2mm layer height with a 10% gyroid infill. Supports (on build plate only) ARE needed!
Thank you armaguedes for suggesting that I make this remix!
