Been playing with TPU filament which for those not aware is a flexible rubber type filament which can be used for printing mobile phone holders and other flexible items, and with some patience front tyres (these at 95 hardness so ideal zero grip).  Below is a 1/24 1980s generic F3 car alongside a SCX Ferrari 1/32 for scale that I have been working on since Christmas which incorporates the TPU front tyres and a TPU rear wing (virtually tear proof). 

Wheels & rear tyres are off the BRM 1/24 Escort MK1 and a NSR Evo 21.4K motor & 8:30 IL gearing drives it along. 

   

Bit of a faff getting the TPU tyres on the BRM lipped rims but a lot easier in this size than the tyres I made for some 1/32 cars where it was easier to design a wheel for TPU than to use the standard shoulder wheels. 

Cheers
