This version uses 8mm rods and 8mm threaded rods? And what about the belt? Can I use a gt belt and 608zz bearings?

Hi HighRoller,

This part is long since obsolete since Serge published later versions and upgraded the SmartRap but yes, a GT2 belt should work. I would still use the 608zzs but I would advise you build and then choose a bearing based on what you have. When I built my 2 or 3 variants of the SmartRap I found that I needed to stack bearings and add a washer on the top to stop the belt from cam-ing out. I would also put a thermoplastic insert in these holes (notice, no captive nut traps on the bottom). BTW, between my 5 printers, and various filament types, I noted that shrinkage varies and sometimes you have to 'work' bearings in. As much as I liked the SmartRap and learned from it, I highly, highly, highly advise you actually do an MPrime One (I have built 2 of them), which derives from the SmartRap.
