Or make some?
Pretty unimpressive as it really only showing you one way to wind wire onto a bobbin.
Lots of details missing to effectively design your own. Wire size and number of turns will determine the electrical requirements for the solenoid. Designing for continuous service Vs intermittent services is also a factor. Material type for plunger is important (soft iron being the best as I recall). To say nothing about the missing physical dimensions for the plunger, stops, etc.
