944 Odometer Gears
Awesome, thanks!
I might remodel in Fusion to make printing on FDM printers a bit more easily, without supports. I'm thinking of modeling the two gears as one part with a bore, then printing another part (a bushing essentially) that creates the center bore and slightly stood off bearing surface.
From measuring, the module of the gears is .4 and .8, right?

I'll have to go back and see if I can confirm that. When I went back and did the 22-tooth gear, I seem to remember that Fusion doesn't record the gear spec, or at least the plug in I used didn't -- but I may be wrong about that. I've printed them on the Bambu with a .2 nozzle, with reasonable success, but love the idea of making them in component parts. I did something similar below and it worked out really well on the Bambu printer....rbwies wrote: Fri Jan 10, 2025 11:40 pm Awesome, thanks!

Update... I printed a set I modeled based on a module of 20 and slapped them in.
Modeled in two pieces, where the larger gear was flat (no dish....not really necessary) with an oval hole, and then the smaller gear with the proper round ID and an oval OD to match the large gear. I made the height of the oval OD a bit longer than required, and 'tuned' the length on some sandpaper to get a non sloppy fit. Realistically, the fit can be sloppy, though.
Printed on my X1C with a .2MM nozzle in matte PLA, pressed together, and installed as a test. Odometer works great now.
The PLA has a HDT of 58*c. It'll probably get squishy in the summer, but once it goes I'll reprint in an ABS or something I can cram through the .2mm nozzle with a better HDT, probably the PC-FR.
I tried a PA6-CF one with a .4mm nozzle and the small gear lost its definition on the teeth.
