Tape Cutter Dispenser Automatic Cutter

🔧 Update V4 – Longer Tape Strips

With Update V4 you can now cut longer tape strips

There are two new gear pairs for the tape cutter

1. 48 mm Gears 
   • 1× small gear_V4_48mm_0.4mm
   • 1× large gear_V4_48mm
   • Result: approx. 48 mm long strips
2. 66 mm Gears 
   • 1× small gear_V4_66mm_0.4mm
   • 1× large gear_V4_66mm
   • Result: approx. 66 mm long strips

💡 Important:

• All other parts remain unchanged – only the gear pair needs to be replaced
• This allows you to flexibly switch between 48 mm, 66 mm, or the standard V3 gears by simply inserting the corresponding gears

💾 Note:

• The gears are uploaded as a separate print profile and can be downloaded individually
• All files are also available individually as a 3mf file
• Pay attention to the correct assembly of the gears: The arrow on the small gear must be centered in a groove of the large gear

🔧 Update V3 – New Small Gear (Improved Cutting Performance)

For all who still desire cleaner and more powerful cuts, there is now a new small V3 gear.
All other components remain unchanged – so only this one part needs to be reprinted

What's New with the Small V3 Gear?

• 5° angled and inclined blade guide
  → The blades are slightly inclined, leading to a significantly better cutting action, similar to a slicing cut
• Assembly marking with an arrow
  → A small arrow is located on the end face
  → This arrow must be positioned exactly in the middle of a cutting groove during assembly
  → Only then will the blade operate in the correct cutting area of the large gear

Advantages of the New V3 Gear

• Cleaner cuts
• Less effort
• Precise razor blade fit
• Compatible with all previous parts

Recommendation

For the update, only one part needs to be reprinted

• 1× small gear V3_0.40 mm gap_new or small gear V3_0.35 mm gap_new  (depending on desired blade tightness)

   

All other components remain unchanged and can be reused

• Note

  - The new V3 gears are already integrated into the print profiles

   

   

Tape Dispenser / Tape Cutter – 100% 3D Printable ⚙️✂️

This fully mechanical tape cutter operates without electronics, springs, or additional connecting parts. By turning the large gear 🔄, the integrated cutting mechanism is moved, and the tape is separated precisely and reliably.
All components (except the blade) can be conveniently 3D printed and assembled without tools. 🧩🖨️

🔩 Included 3D Printed Parts (13 parts)

• 3× nuts
• 3× bolts
• 2× adapters
• 2× gears (1× large, 1× small) ⚙️
• 2× outer parts (housing / casing)
• 1× tape holder / roll adapter

📁 Additional Variants

• 🦷 Alternative small gear with 0.35 mm blade gap
   → For a more precise fit depending on printer tolerance
• 🎨 Design variant with cut-out side panels
   → modern look + lower material consumption

⚠️ Required Third-Party Part

• 1× utility knife blade (standard, 9 mm)
  Recommendation: approx. 4 segments

🔪 Inserting the Utility Knife Blade (Important!)

• Insert the blade from the front or place it further forward into the groove
• Then push it all the way back to the stop
• The blade is deliberately seated 1–2 mm recessed so that nothing protrudes – for added safety
• Always insert with pliers! 🧰⚠️
• Push the blade all the way to the back with pliers so that it sits correctly and securely.
• Optional: Wear protective gloves

• Check: A blade segment must sit in one of the grooves of the large gear → this is where the cutting process takes place ✂️

   

• 

Fit Notes

Tolerances may vary depending on the printer

• If the blade is too loose → use a very small drop of glue
• Always be aware of the risk of cuts when handling the blade 🩹
