Shock absorber rubber

Recently my old timer Jeep lost the rubbers that go between the shock absorber and the mounting pin. These parts are hard to come by and our local dealers want to sell the complete shock only. So I printed them very successfully with semi flexible TPE filament. The specific filament I used had a hardness of 45D. This filament will not work on all extruders. Bowden becomes very tricky. I made a modified part for the standard bowden extruders found on many cheap delta printers. This modification allows flexible filament to be printed using a bowden extruder. Printing speed is very slow. 1cm/s can be reached; however, I tend to print at 5mm/s which gives the most reliable results. It also allows the rubber to melt into the previous layer giving a much more solid and technically sound part. The semi flexible rubber TPE works well on a heated bed on 50'C with masking tape, and on the masking tape a thin spread out layer of contact glue (the yellow sticky stuff you use to glue carpets or sho
