I'm uncertain of proper etiquette for updating things, so I'm just going to toss up a changlog and the new files up here.
Removing the square nut gear (it's useless)
Adding a large shaft driven gear
tweaked the mount plate (matched the bearings)
added a high clearance b'struder arm
The new shaft driven gear is center-able for all those printers out there that struggle to print a tight fitting shaft bore. The shaft setup handily outperforms a m5 hex bolt setup, I've been getting excellent performance for over month.
new parts list.
4x m3 socket head bolts (5mm-7mm)
2x 625ZZ bearings
1x mk8 hob gear
1x 5mm shaft (50mm minimum) or 1x M5 hex bolt (40mm minimum)
2x-4x M5 washers (spacers)
3x M3 nuts
3x M3 7mm bolts
if your printer rocks you only need 1 M3 nut and M3 7mm bolt
old stuff:
The B'Struder is awesome, Full credit to tempo502(http://www.thingiverse.com/thing:711401).
I like gears and I like torque. my extruder stepper has nether. To solve the problem I slapped a slip optimized 5:1 gear drive onto a B'Struder. I can't speak to gear longevity, as performance was all I cared about.
I used PETG.
You'll need the B'Struder arm( go pick one of tempo502's) and it's hardware
a 16x5x5mm bearing
a 10x4x5mm bearing
4 8-10mm m3 machine screws
4 m3 washers
1 35-50mm m5 bolt.
mk8 hob gear
3-5 m5 washers(used as spacers for hob placment, bearing clearence, and spacing the large gear from the mount plate)
m5 hex or square nut
I reserve the right to change anything, at will.
edit: added a M5 hex bolt version, as most people don't have hundreds of mildly useless square nuts lying around.
