InMoov Bicep Servo Holder for Turnigy™ MG959 Servo

thingiverse

After one of my arm's servos failed, I start looking for a replacement that would get in stock immediately because my ten original backordered servos won't be shipped for another two months at least. In that case, I decide to purchase the Turnigy MG959 http://www.hobbyking.co.uk/hobbyking/store/__40285__Turnigy_8482_MG959_V2_Alloy_DG_MG_Servo_30kg_0_15sec_78g.html\nThis full metal servo is quite impressive for its price, given its overall design. The servo itself can be easily disassembled, a vital feature I appreciate deeply, because it allows me to drill out carefully the pin in the main gear if continuous rotation is needed - and if so, I'd rather just cut off that part completely. For connecting the pot cable, you will need to grind a small opening on one side so as not to solder, and then clamp it into a 3-way dupont connector instead for simplicity's sake.\nPlease note, this servo cannot function alongside the original with no modifications whatsoever made - at least, I was unable to find any setup which worked well with each other. In place of the existing housing on my MakerBot arm model (made using Replicator 2X settings as noted below), a completely revised holder is required: its increased size has enabled it preserve exactly the same angle and proportions we'd originally intended to achieve by using this arm in my setup, thus preventing the structural deformation I observed when attempting earlier versions. Also note that these new servos may not behave optimally under tension - a design element that made it all worthwhile but still problematic nonetheless; it adds bulk however which serves its purpose here well enough considering my goals and needs were more about maintaining optimal performance within budget rather than optimizing pure performance capabilities alone. Print Settings: Printer Brand: MakerBot Printer: MakerBot Replicator 2X Resolution: 0.1 I have always taken to printing this particular part out at 100% in-fill rate for increased stability - ever since breaking countless bicep pieces, mostly because the arm servos weren't cooperating fully during printing operations.
