110mm Kingsize Cigarette Roller

110mm Cigarette Roller – High Precision

This is a fully functional cigarette roller for the 110mm (King Size) format. The design is engineered for durability and smooth mechanics. For the gears to run smoothly and the fabric not to snag, precise print settings are crucial.
 

🛠️ Assembly

1. Print all parts (plates 1 & 2 & 3).
2. Carefully remove the tree supports.
3. Attach the small gears to the outside and the rods to the inside.
4. Insert the rolling fabric (ideally a standard 110mm replacement fabric for rolling machines).

🧵 Material Used & Why

For this project, I used Extrudr PLA NX2 (in matte black). Although regular PLA also works, I recommend NX2 for the following reasons:

• Mechanical Resilience: Since gears mesh here and pressure is applied to the rollers, the higher toughness of NX2 is an advantage.
• Appearance & Feel: The matte finish not only provides a sophisticated look ("stealth" aesthetic) but also forgives visual imperfections better than glossy filament.
• Dimensional Accuracy: The parts fit together perfectly, which is essential for a mechanical print.

⚙️ Print Settings (Important!)

For the roller to function as smoothly as mine, I made some specific settings in the slicer (Bambu Studio / Orca Slicer). Here are the details based on my print profile:

• Quality & Layer Height:
  • Printed with 0.12mm layer height ("High Quality" profile). This is extremely important for the fine teeth of the gears and the roundness of the rollers. At 0.2mm, the gears might snag.
• Surface Finish (Ironing):
  • Ironing: ACTIVATED.
  • I set "All surfaces" to be ironed (30mm/s, 15% flow). This ensures that the flat surfaces of the housing and gears become extremely smooth and generate less friction.
• Speed:
  • I reduced outer walls to 60 mm/s to guarantee the dimensional accuracy of the fits.
• Supports:
  • Type: Tree (Auto).
  • Very important: The top Z-distance is set to 0.12mm (identical to the layer height). This allows the supports to hold the part cleanly but to be removed almost without residue after printing.
• Build Plate Adhesion:
  • For the upright rollers, I recommend a brim of approx 10mm (as set in the profile) so that these tall, thin parts do not tip over during printing.

Happy printing! If you like the model, I'd appreciate a rating and a boost 🚀.
