Soft Tape Measure Spool

https://www.thingiverse.com/thing:3603000 was great! The replies from https://www.thingiverse.com/Sadhaka were very helpful, and uploading the Solidworks parts and assembly files really helped.

To get my head fully around the design, I re-created the parts in Inventor. I ultimately wanted the handle base to screw in, instead of gluing it on.

So after I had it all modified and modeled in Inventor I took the "Handle1" file and added modeled M10 x 1.25 threads in Fusion 360 (I uploaded the Inventor files and the Fusion 360 ones as well).

In the photos it shows the assembly with the first modified handle base, but I used the one that has the hex base instead of the one without it. The model files are up to date.

The handle base files are both threaded in the model. For the part it screws into, I removed the sprocket teeth, made it 4mm thick, and reinforced the hole that was to be threaded in the model to have more infill around where the threads were to be cut. I actually used
