Firebay Peanut MG90 Servo Mount by klauscon

Last crawled date: 3 years ago

Redesign of earlier MG90 servo mount to be integrated with the Firebay Peanut Fanduct remix to use 5015 blower fans, found here: https://www.thingiverse.com/thing:2851423. . The entire design can now be printed without supports, although some cleanup may be required to make sure the channel through which the switch mounting arm passes is smooth and clean.
Please refer to https://www.thingiverse.com/thing:2744300 for BOM and fiirmware , especially details of microswitch and servo. The design is for a MG90, which is still dirt cheap and gives much better accuracy than a SG90. The microswitch is handpicked for extremely low operating force, which is important when you are pressing down on a print bed. Please do not ask if you can use other switches - you can use whatever you want, the arm is easily redesigned to fit any size switch, but your accuracy will suffer a LOT if you go for other switches.
Print the gear at the finest resolution your printer can muster (0.12 is perfect) and with 0.3 extrusion with so that the spokes are clean and strong. 100% infill for gear and arm. 20% for the main mount. Print the main mount on flat back.
