... been working on the design of this servo mount for a while and thought that Templot users may appreciate the better relationship between servo rotation and the short travel of this mount compared to other mounts. For a 90 degree rotation the rack movement is only 2.5mm. The top of the rack has holes at 18mm and 9mm centres that enable 4mm or 2mm switch blades to be driven independantly but together thus avoiding fatigue failures of soldered tie bars. I have also incorporated holders for Hall Effect sensors or micro switches to allow position feedback. 3137_301828_240000000.jpg I have attached in the message below an article that will appear in the December edition of the MERG Journal that describes the development of this mount and gives more details of it. I have attached the STL files for 3D printing the mount. The Mount itself can be printed in PLA with a 0.2mm layer thickness and 0.4mm nozzle. The gears are best printed in PETg with a 0.15mm layer and 0.25mm nozzle although PLA seems to be OK. If you have any comments or questions about the mount please post them here. ...
