Roller Bearing Core for SPANNERHANDS Spool System MK6 by ApertureEngineering

Last crawled date: 3 years, 1 month ago

This is a ball bearing filament spool core for the nicely designed SPANNERHANDS Spool System MK6. The addition of ball bearings prevents binding and allows for ultra-smooth rolling of the spool.
The core diameter has been reduced from the original 52mm down to 48mm to be compatible with a greater number of filament spools.
The roller core takes 2 bearings with the following measurements:
32mm OD
13mm ID
10mm Width
A second version is available for bearings with an ID of 12mm.
The bearings might fit a little loose to account for tolerances in different printers. This can be countered with a few strips of electrical tape if you want to bearings to fit snugly in the core.
The mounting holes on the screw cap are spaced at 51 mm (2 inches) to allow for mounting any of your custom handles.
