Ya, I figure I should have some type of heat sync and/or fan on the motors of the mini kossel that I am building. I've got it all put together, just waiting for the RAMPS board to come in but if it takes longer I might borrow the RUMBA off my SD2. It will have the FSRs for auto bed leveling. I think it will be a pretty good printer when its done. I actually canceled my SD Press order when I saw the video of the autoleveling. The probe design just looked kinda flimsy and I decided I would just build a delta printer with FSRs. I don't really care to ever own a printer without auto bed leveling again. If it works really well, my SD2 will probably be sold for parts.
Ward, thanks for the dimensions. Wompus, my motors on the kossel build don't have bolt holes in the back so I will need to secure it to the motor with adhesive, which the ones I linked from Aliexpress have.
