This is an updated Saddle for @Extrutim Cheap Filament Storage Box, and @PhilCaruso AutoRewinder
I think it looks nicer and is more stable, and fits the base better.
It's an triangle tower style saddle for the Auto-Rewinder that fits Extrutim's Dry Box base without damaging the bearing holders of the base, and without needing the cross bar. It has sleeker geometry using less material. It is easier to print without the face fillet on the edges that are on the build plate. The original saddle had wheels that kept breaking my drybox base's 17mm bearing holders.
Changes:
Smaller diameter connectors with 0.10mm more tolerance on the "wheels" Their external diameter is now 16.6mm to fit into the 17mm bearing holders in the base.
Larger compression slots: The cross-shaped compression cutout is 1.5mm and has more aggressive fillets to round the compression points.
Removed the fillets on the face that sits on the build plate.
Updated the main geometry to increase stability and aesthetics, using less filament,
Needs Supports. Print with default Prusa Slicer "snug" supports, on build plate only, for easy clean removal.
I have printed with up to 0.40 mm layers using 0.6 nozzle, or 0.20 layers using a 0.4mm nozzle if you want to be fancy. Looks nice in Prusament PETG-CF, or in Galaxy Black. PETG or PLA will work.
Thanks @PhilCaruso for the original saddle design and its step file, and @Extruim for the Cheap Filament Storage Box (but where's your step file though?)
