PRUSA Filament Cartridges – Modified for Readily Available Push Fittings

This is a modified version of the popular Prusa filament cartridges. I’ve made some small changes so that they fit standard push fittings and bearings that are easy to find online (e.g., via Temu or Amazon).

What’s Changed?

The push fitting holes have been adjusted to fit fittings with the following dimensions:

• Diameter: 6 mm
• Length: 9 mm
• For 4 mm PTFE tubing

The push fitting holes have been adjusted to 6mm:

• PC4-M6 connector 4mm tube

The axle is now integrated into the plastic part, so you only need:

• One 693ZZ bearing (3x8x4 mm)

The image shows two different push fittings – the larger one fits this design.

Parts Required

• 5 pcs M3 x 6 mm screws
• 3 pcs M3 nuts
   
• 2 pcs push fittings – Temu ID: MD2739951
   
• 1 pc 693ZZ bearing – Temu ID: HQ13888
   
• PC4-M6 connector 4mm tube - Temu Vare-ID: NQ1233359

Print Settings

• Recommended material: PETG
• Layer height: 0.2 mm
• No supports needed
• 3 perimeters for strength

This is a small but practical update that makes it easier to use off-the-shelf fittings without any special modifications.

PRUSA Filament Cartridges – Tilpasset til Push Fittings fra nettet

Dette er en modificeret version af de populære Prusa filament cartridges, hvor jeg har lavet små ændringer, så de passer til almindelige push fittings og kuglelejer, som er nemme at finde online (f.eks. via Temu eller Amazon).

Hvad er ændret?

Push fittings hullerne er tilpasset fittings med følgende mål:

• Diameter: 6 mm
• Længde: 9 mm
• Til 4 mm PTFE-tube

Push fittings hullerne er tilpasset 6mm:

• PC4-M6 connector 4mm tube

Akslen er nu integreret i plasten, så du kun skal bruge:

• Ét kugleleje 693ZZ (3x8x4 mm)

Billedet viser to forskellige fittings – den stor passer til dette design.

Dele du skal bruge

• 5 stk. M3 x 6 mm skruer
• 3 stk. M3 møtrikker
   
• 2 stk. Push Fittings – Temu ID: MD2739951
• 1 stk. kugleleje 693ZZ – Temu ID: HQ13888
   
• 1 stk. PC4-M6 connector 4mm tube - Temu Vare-ID: NQ1233359

Printinformation

• Anbefalet materiale: PETG
• Laghøjde: 0.2 mm
• Ingen supports nødvendige
• 3 perimeters for styrke

Det er en lille, men praktisk opdatering, som gør det lettere at bruge fittings fra nettet uden specialtilpasning.
