Spooler mini cho thước dây mềm (Mini flexible tape measure spooler)

This is a spooler I designed for my flexible tape measure to be able to put it in a bag and forget about it. I first tried to find a model online but they were all either flimsy or had an open design.

The spool is protected, winds up really easy and once assembled the tape measure can't be pulled out:

It needs 2 m3x6 bolts to hold it together, see pictures for assembly. The metal part of the tape measure can be at most 12mm wide and 10mm long so it is mainly for the ‘tiny’ variant. I have added the source files for you to edit.

Update: Three extra sizes! I have designed the original for my own narrow and thin tape measure to be as small as possible but I have added a spooler with a wider diameter (35mm) in three widths. Disclaimer: I have not tested these since I don't own these tapes, but when the metal part fit it will be ok I think.

Happy printing, and if you like my models you can follow me for more awesomeness!
