Rubber band Bow - Toothpick + Cotton swab

Easy to print Rubber band toothpick bow

You can use any toothpicks up to 2.7mm diameter (The barrel hole is 2.8mm).

Recommended rubber band dimensions = (1.5mm thick - 50mm diameter). Even larger or smaller rubber band works.

There's 4 versions:

V3 Large is concidered the standard version as this works with most office rubber bands.

V2 has smaller distance between forks so more suitable for even shorter rubber bands so i am keeping this file here.

V3 Large - Thicker rubber band has more space for thicker/flatter rubber bands - Not tested

V3 Cotton swabs has larger hole diameter so you can shoot cotton swabs with it, but it's less suitable for toothpicks.

Printing:

• 0.16-0.2 layer height is recommended
• Remove the brim after print (see pictures)

UPDATE 24/12/09 - Cotton swab model & alt model for thicker rubber bands

• Added a version with larger hole so you can shoot cotton swabs with it. More suitable for wild kids. - Hole diameter (3.5mm)
• Added a version with more space for thicker flat rubber bands - Not tested!

UPDATE 24/12/06 - Larger bow added, longer forks, more power.

• Added a larger bow version with added height to the thumb/finger grip for better ergonomics
•  Forks are 20mm longer which gives most normal sized office rubber bands more power.
• Takes 30min to print

UPDATE 24/12/02

• Hole decreased from 3mm to 2.8mm to help with accuracy.
• Made minor changes to the model to make it more appealing and also made front longer to avoid finger being placed over the barrel.
• Added brim to the Rubber band brackets to connect them with the rest of the model to aid in its survival.

Please let me know if there are any problems or improvements to be made.
