Mini Track Loader RC Micro Servo SG90 HXT900
thingiverse
I designed this based on the "Mini Track Loader RC" from Zedpi. You can use the lego chain and all the other parts from Zedpi's design (https://www.thingiverse.com/thing:1000713). So it is only slightly larger as the original one from Zedpi. The idea is from Zedpi, I only redesigned it that standard micro servos fit into it. I use very cheap ones from ebay "TOWER PRO™ - Micro Servo 9g - SG90", but I recommend Hextronik HXT900 Micro Servos they are a little bit better in my opinion. You have to modify it that the servos for the chain will be continuous (please search on youtube how to do that, there are a lot of videos).
