Boost Me Boost = 43 g of filament :) Membership Commercial License EDIT 7. 2. 2025 - I made Universal Bottle Cap Opener that opens caps with diameters of 27 - 35 mm.

EDIT - PRINT PROFILES - I have added new print profiles with different diameters for larger and smaller caps. I recommend printing the M size first and then deciding which size is ideal for you.

XXXS - 28,6 mm diameter

XXS - 28,8 mm diameter

XS - 29 mm diameter

S - 29,2 mm diameter

M - 29,4 mm diameter (recommended)

L - 29,6 mm diameter

XL - 29,8 mm diameter

EDIT 31. 1. 2025 - It seems that there is a problem with the diameters of PET bottle caps from different countries . This problem can be solved by scaling the tool up or down . For my cap with a diameter of approximately 29.9 mm , the inner diameter of the tool is 29.4 mm . I would like to create more print profiles for different types of PET bottles from different countries, but I do not have the opportunity to physically test them. If you find the right scale for the right diameter, please let me know!
