Sony Walkman WM-1 FF/REW Linkage

NOTE:  Due to material availability changes and customer concerns regarding the durability of the new materials offered, I have had to make the default material PA-11 SLS.  Smooth Fine Detail Plastic is no longer available and it appears the new Ultra Clear Fine Detail plastic is having rigidity issues.  I did have a request for a metal alternative and made polished bronze-steel available however I have not test printed this material yet.  Any suggestions are always welcome!  :)

This is a replacement "hook spring" linkage to replace the original in the Sony model WM-1 Walkman cassette player.  This linkage retains a spring (not included) that causes the orignal part to break as it ages.  This part is reinforced in key areas and should repair the operation of Fast Forward and Rewind as well as last much longer.  Most WM-1's suffer from this problem.  This part has been tested in my personal WM-1 Walkmans with great success.

Thanks to a helpful customer, it is known that this part also fits the following SONY models:
TCS-300, TCS-310, TCM-111, TCM-121 and TCM-131

NOTE:  Due to slight variations in the printing process, and to avoid a loose fit, the hole may be slightly too small when you receive the part.  A drill bit can be used to ream the hole out to a proper fit.  Repair experience is required for installation.  I cannot be held responsible by damage caused by improper installation of this part or damage caused in the process.

Thanks for looking!
