Tarmo4 Accessories and Modifications

thingiverse

I've made modifications to numerous Tarmo4 original parts for various reasons. I've also designed a few useful and aesthetic add-ons as well. Please be aware that modifying these parts is in no way an attempt to undermine the original designs or Kris Shellman, the person who created them. The Tarmo4 is an amazing feat of engineering, and I'm just happy to contribute to the community. Tarmo4 17mm Hex Wheel Bushing_Hex Nut Bushing for 1:8 scale wheels that facilitates the installation of a 4mm Lock nut to tighten the wheel to the wheel axle. This bushing is used when you're not using Tarmo4 17mm Hub Extender. Tarmo4 17mm Hex Wheel Bushing_Socket Head Bushing for 1:8 scale wheels that facilitates the installation of a 4mm x 12mm socket head screw to tighten the wheel to the axle. This bushing is used when you're using Tarmo4 17mm Hub Extender. Tarmo4 17mm Hub Extender Extender that allows the use of 1:8 scale wheels with no offset. This part gives the front wheels clearance to turn without impedance from the steering linkage. To use this part, replace the hex head bolt that's recommended for the wheel axle and use a 4mm lock nut in its place. A socket head screw can then be slipped through the slot in the extender and tightened into the nut. Another 4mm lock nut can then be inserted into the captive nut cutout on the non-slotted side of the extender to facilitate the tightening of the wheel using a 4mm x 12mm socket head screw. Pair this with Tarmo4 17mm Hex Wheel Bushing_Socket Head. Tarmo4 17mm Hub This part allows the use of 1:8 scale wheels with a 17mm hex. Pair this with Tarmo4 17mm Hex Wheel Bushing_Hex Nut. Tarmo4 Open Diff Bell Housing_2mm Screw Modified open diff bell housing that allows the installation of a 2mm socket head screw and nut instead of a thick paperclip or wire to secure the Traxxas parts to the bell housing. Tarmo4 Modified Wheel Axle Modified wheel axle with a positive stop for the bearing. The original part tapered, making the seating of the bearing dependent on printing accuracy, resulting in inconsistent fit. Tarmo4 Front Differential w/ Screws Modified front differential gear that allows four M2 x 12mm screws to be installed to solidify the front differential assembly. Tarmo4 Dogbone (Reinforced) Reinforced version of the dogbones to make them a bit beefier. Recommend printing these out of nylon if possible as they have proven to be high-stress items. Tarmo4 Servo Mount w/ ESC Mount Remix of the original servo mount that includes a convenient place to mount the recommended Hobbywing Quicrun 120a ESC. There is a surface where the capacitors can be mounted to the side of the ESC, as well as a surface where the switch can be mounted vertically to the rear of the ESC. Tarmo4 3mm Rod End Articulated rod end for the connection of the steering servo to the steering linkage. Use two of these and an appropriately sized length of 3mm threaded rod. As of May 21, 2020, these parts have all been tested to work properly. I will update the page if changes are made to any parts and welcome any and all criticism and direction. Thanks to everyone who has contributed to this project!
