I got chance to salvage my old fauhalber 1717t motor from my mouse last year so I don’t need to purchase new one. All the holes for shaft and mounting are 2mm diameter and fit well with M2 screws.<\/p>\n

However, the shape I designed to perfectly fit motor is a little smaller than it supposed to be. I cut off a 17mm diameter circle on one side of motor mount so the 17mm diameter motor can perfectly fit into that concave. But I put too much expectation on high precision 3D printing and the concave was a little smaller than 17mm.<\/p>\n

In order to make the motor closely attach to the mount, I had to use dremel to slightly expand the concave. Though it was ugly after polishing but it was actually hiding inside when the motor was mounted.<\/p>\n

Here is the comparison between expanded and unexpanded motor mount<\/p>\n

I can finally mount my motor onto the mount. the hole I reserved for 4 M1.6 screw fit tightly there, so for the M0.5 12T gear.<\/p>\n

\"IMG_0816_resize\"<\/a> Then I tried to put ball bearing onto the shaft, secured by M2 screw at the end. I will use locker nuts for my final version.\"IMG_0808_resize\"<\/a> \"IMG_0811_resize\"<\/a><\/p>\n

What I am still unsatisfied so far is the washers I used to support between screws and ball bearings were bigger as I wanted. the outer diameter is 3.7MM for a M2 washer is kinda unacceptable for me, I am still looking for suitable material for smaller M2 washer.<\/p>\n

I am still waiting for rest of the parts, once the DS 0.5-40 gear got delivered, I will try to put them on to see if all gears fit each other(I will likely fit each other well but I still want to know the results).<\/p>\n","protected":false},"excerpt":{"rendered":"
