Whoop MG/5.0, Adapter Cho Dây Đeo 4.0

Optimised for printing with a .4 nozzle with a line width of 0.4 in PETG (Dry). Any layer height should be fine, I used 0.28.

The adapters should be a snug fit and slide in without a lot of force, if they are too tight or too loose try adjusting flow rate, or if your slicer has the ability use contour compensation to get the correct fit. A light sanding may be all that is needed for a tight fitting adapter.

Aligned or Nearest Seam position works best for fitting.

If you have issues with bed adhesion for small prints use a brim for extra adhesion.

Assembly:

Locate 4.0 band semi circular end onto the MG/5.0, it should locate in the top groove.

Do not force the spacers past half way or less if they are not sliding in easily, remove and either give the outside a light sand or reprint as described above. 
Install one of the spacers, they will only go in one way. Install the other spacer.

Make sure the MG/5.0 is central to the 4.0 band end.

After installing the spacers make sure the band is secure by giving it a gentle pull. (During testing I applied a lot of force trying to pull them apart and band and Whoop held together)

To remove just slide the band or Whoop sideways, the spacers will try to make a break for freedom so best to do it over a table or bench.

I am happy for people to print extras for friends and family, just don't sell for a profit.

Constructive feedback and user experiences welcome, I can potentially add a small, medium and large option to help with variances between filament brands and printers.

Print and use  at your own risk.
