Gold Series anti flex motor cages for Rat Rig V-Core 3

thingiverse

I found under some situations the standard motor mounts were flexing and over time they could droop, especially the rear one. These mounts also have flanges that sit on top of a 3mm floor panel to help seal the enclosure and provide further additional support for the motor mounts. I also found the irregular shape of the original Rat Rig motor mounts made cutting the floor panels more difficult so these have have a simpler shape. <b>The non flex front motor cages have:</b> 1. Wider mounting holes spacing to make the mounting more rigid. 2. Sealing flanges to cover gaps between motor mount and floor panel. 3. The sealing flanges also help support the motor cages on the floor panel. 4, Front motor mounts have detents that fit into the extrusion slots to give more rigid mounting. 5. A simpler cutout shape for the floor panels. In addition both versions of the rear motor mounts: 6. As per the photos are designed to be used with an extra frame extrusion to prevent droop. The front of the motor mount sits on top of this extrusion to prevent it flexing. If you don't want to install this extra extrusion rail I have another version of the rear motor cage that is better than standard, but is not stiff enough to be part of the Gold Series of mods. 7. The motor can be moved back and forth in it's pocket to better line up the rear leadscrew. <b>Alternative rear motor mount for centralised leadscrew.</b> I have also included an alternative rear motor mount that centralises the rear leadscrew instead of having it offset. This must be used in conjunction with a bed arm that has been designed to centralise the rear lead screw. If you would like a bed arm with the centralised lead screw please email me Liam@FastBikeGear.co.nz for the printing files. If you decide to contribute to my coffee fund to keep me up late at night doing more of this stuff I would appreciate this, but there is absolutely no obligation for you to do this.
