• Play between parts has been eliminated

• The design now has smoother edges

• The filter is slightly smaller

• The sponge holder has been redesigned

• Sponge hooks have been added, so the sponge is held even more securely

• The filter can remain installed while feeding new filament

• Most importantly, it still locks onto the fitting and prevents it from popping out

Printing recommendations:

• I now recommend printing in PLA

• I recommend trying vertical printing

• Supports are required

• Remove supports carefully

• All other settings can remain default

Use a 2 × 1.5 sponge piece and magnets of your choice.

Please note!

Each filter has its own design. There are 6 different variants in total.

1 — Filter with a latch and a pin

Advantages:

Does not require magnets, provides a very strong locking connection.

The filter will no longer open on its own, even when the filament spool runs out.

It may be difficult even for you to open it — use tools.

The design should be suitable for printing on printers with poor tolerances.

2 — Filter with a latch and a locking hinge

Advantages:

Does not require magnets, provides a very strong locking connection.

The filter will no longer open on its own, even when the filament spool runs out.

It may be difficult even for you to open it — use tools.

Your printer must have very good print quality.

3 — Filter with a 5×2 magnet and a pin

Advantages:

A simple and reliable design, but your magnets must be strong enough to prevent accidental opening.

The design should be suitable for printing on printers with poor tolerances.

P.S. I have included STEP and Shapr3D files — feel free to modify them to match your magnets.
