Download Free 3D Model Tank2 undated Gear Cases for Kyosho RF006 worm gear set 3D Print Model

Summary
Hey back at it again with the original tank. Have gained a lot of knowledge in the last three years about gear boxes. Going back over the original tank and redoing some things to make it better, lighter, cheaper, easier and stronger. Going to try to keep the original looks and suspension the same. This new gear drive design I have had a lot of luck with and the Kyosho gear drive set has been proven to be indestructible. The new design uses fewer parts and is stronger than the old gear box. Uses a pair of 6x15x5m sealed ball bearings of the worm gear and two 6x16x5m sealed bearings for the shaft. My RF006 Kyosho gear set has the bearing tab cut off the one end. I have supplied a spacer to take up the slack but the original gear may fit in the case without removing the bearing tab. Make sure the worm wheel/axle is centered on the worm gear. There is a access plate that uses two #4×1/4 flat head sms (just in case the screw ever comes loose on the axle gear). Uses a pair of 6-32×1-1/2″ machine screws per side to go through the case and frame. Two #6×1/2 screws for the top frame, four #4×3/4 sms for the inner case and three screws per side #4×3/8 sms for the back plate and two #4×1/4 sms screws to hold the inner bearing and give you some adjustment. Drill #6 screw holes at .140″ (#28), #4 screw holes at .120″ (#31), #6 thread holes at .1065″ (#36) and the #4 thread holes at .086 (#44) on the flat and .093″ (#42) through the layers to keep from splitting.
Print the inner cases with raft and exterior support. Print the outer cases and the parts without raft. I use 2 extra shells and 20% fill. Break off extra tabs and buttons for support.
Have CNC machines up and going finally and will have frames rails and motor plates available on eBay for this tank and probably the old tank also. Search for fastmike tank2.
