That's an interesting concept. I wonder how I'd attach something like this to my rails. This requires more research.
I don't really know much about gears (or rack and pinion). Anyone care to offer advice on pitch, pressure angle, or whatever, for this purpose? It looks at a glance like Amazon has some options, though they're a bit expensive. This might be a future upgrade.

I'm guessing this is also the case. Maybe OP could swap to a new gear on the extruder first but a BMG clone is like only 22 bucks if OP want's to go that route. Maybe trying another slicer first is a good idea too.
I have been thinking that same thing all the way down here, BUT- the thought just occurred to me. Would this tool be less awful if all but the furthest out pivot used mating teeth? Maybe like a bevel gear? I am still against it, anybody really concerned about a non-90 angle cut is still better off with a scribe..but what if? Just what if?
Depth is 1mm along the side. The worm gear does have a key (threaded screw) but the shaft would still need a flat surface for the screw to hold on to I suppose. I don't have the equipment so I'll check if any local metal working places (Houston, TX) could help me out.
They probably use a 90 degree gearbox to change the direction of motion. The gearbox probably has reduction gearing to make turning the handle easier.
There are many specifications needed to describe those gears accurately. Have a look at these for some of the specs relevant to your application.
