Wiper Blade Retaining Peg (TPU) Lucas/Trico Type For 1940s/1950s Classic Cars.

Designed to replace a broken rubber retainer peg for a 1947 Lanchester, replacement rubbers are available for about £5 a pair, but this amount of TPU costs about 0.5p (GBP £0.005) each so it had to be worth a try :o)  This is the finished version which has now been tested and fits perfectly - very snug to get past the final part of the taper and then pops into place. Obviously there may be issues if the Sun is extremely hot, only time will tell !

May well also fit other cars with similar flat screen wiper blades which have a slot-type connection between the blade and the wiper arm, with a hole about 4.6mm diameter for the peg to fit through. If you have a similar design but the hole is a slightly different size, I have made this model 100% parametric so you can change anything you like in Fusion360 - all lengths and all diameters without having to edit the sketch, just modify the relevant size via the FX-parameters option. 

Very unlikely to work with a hard plastic, this is designed for TPU. I used Eryone Black Shore95A filament with a 0.4mm nozzle, 0.2mm layers, 4 walls. Everything else standard slicer settings for TPU, no adhesion or support needed, My Elegoo N3Pro prints TPU perfectly with a cold PEI print bed - perfect adhesion with no heating - heating the bed can cause TPU to bond permanently to a PEI bed and ruin it. 

If you find these fit your model, please post your "make" of the print and mention your car make and model so others can see it could work for them too.
