A 3D printable adaptor which allows a "Schrader" type automotive air line to seal on to a "Presta" type valve stem.
Used on tubeless bicycle tyre service this allows the tyre to be fitted to the wheel rim bead using a compressor or compressed air line. Sometimes just a little more air volume is needed to help the tyre bead "Pop" onto the wheel rim.
This is drawn in Fusion 360 using an 8mm x 0.8mm thread for the external thread. This is not the actual non-metric dimeion of the "Schrader" automotive thread but the tyre inflator valve will fit on to this.
The internal thread is designed to thread on to the valve stem with the valve core removed. If you are servicing a tubeless tyre you will be adding some sealant through this stem with the valve core removed and this adaptor allows higher air flow using a compressed air line to help seat the tyre bead while the valve is not fitted.
