In developing my 3D printed spindle design I’ve had three sizes printed up. The smallest works well, but the bore of the shaft is a little small. The largest version had a good sized shaft, but wasn’t as sturdy and was a little unwieldy. I’m hoping this new middle sized version is the winner.

First, though, I need to sand down the printing artifacts, which are small bumps of filament that didn’t quite go where they were programmed to go. Filament is like that. Resin printing has less of these artifacts than filament printing, but the PETG filament is tremendously more durable. Plus it makes the spindle look like a calcite crystal. Nice.
