Tacx Neo (Gen 1) Rocker Capable Foot

thingiverse

Throwing this up here while I tinker some more. Gen 1 Neo replacement foot option, take out supplied plugs, slide these in, throw ball of choice in the "cup" and set the trainer on top. Tennis ball original idea/size. Haven't tested myself yet (8/13/2020), should have access to printer next week (and tennis balls). Very rough design, hopefully works better than an entire rocker plate build. Hint - you need 4 of these. Printed with 25% infill, and a 5 shell. Haven't tested yet. Update 8/14/2020 - Printed 2, tennis ball fits perfectly. Feet fit into Tacx Neo foot holes with a smidge of wiggle, I'm increasing to 34.5mm for a hopefully tighter fit. It'd work as is, but this would help with positioning. Also added a "2" to the top of the sphere so I know it's the 2nd iteration design. Update 8/18/2020 - 34.5mm diameter of foot plug too big, made it 34.1mm and will probably stop messing with it. Left the "2" on there as well. Update 8/23/2020 - Tested 4 with brand new tennis balls, see picture. 25% infill, 5 shell, feet did not break, however of note, I'm 150 pounds. It's not a "rocking" motion as in side to side, it's more just exaggerated movement. It is noticeable going from no feet to tennis ball feet though, I did it a few times over. So, I'm going to leave the design for now.
