myminifactory

Update (22/10/2020):The following parts were updated (printing default orientation and support optimization): SPRING SUPPORT_1;SPRING SUPPORT_2;KNOB_EXTENSION. Update (17/06/2020):The following parts were updated/added (mainly tolerances): LOGITECH REPLACEMENT PART;SPRING SUPPORT_1;SPRING SUPPORT_2;ACTUATOR_1;ACTUATOR_2;KNOB_EXTENSION (Still want to design 2 more with different heights (specially for H pattern use)) . To lock the knob, you will need a M4x40 screw! -------------------- Decided to create a versatile sequential shifter mechanism, that could be easily installed on a Logitech G Shifter, depending on which car or game I wanted to play.A simple rubber band or spring would a similar job ( (I had it installed on my shifter before), but I find the feeling/force of this mechanism more "realistic" and robust, and besides that, we have to make some good use of our 3d printers, right :) . Although this is still a WIP design, it is already functional, so it should work just fine.But some optimizations are yet to be done, so further development and community feedback will help with these points: Replacement Part Concentricity;Overall Rigidity (might create a connection between both "spring supports") Wait for further updates ;)"; Tolerances; Printability; Design a Knob extender. You should be able to glue the existing boot to this new replacement part. I haven't tried it, so I cannot guarantee it will work. 1x13x60 Springs:https://pt.aliexpress.com/item/33004430576.html?spm=a2g0s.9042311.0.0.2742b90a7MZrfI Youtube Video:https://www.youtube.com/watch?v=sGcbtzC4YmU
