Designed this for the SV02 when I changed it to direct drive, using concepts from a couple other filament guides. My SV04 IDEX has runout sensors which keep the filament neater when printing and wanted similar for the SV02.

There are two styles of rollers, one that uses a 608 bearing or a fully printable one. The bearing version will obviously be smoother running. You'll need two of whichever roller you choose, 2 of the axles and unless you have some laying around, 2 of the M3 T-nuts. The t-nuts require an M3 nut and you'll require a couple 10mm M3 screws to mount it.

Infill is your call. I accidentally left mine set at 100% from the previous job, but 50% or more should be ok.
