PET Bottle Opener/Closer #2
Description
**This PET bottle opener/closer is the most advanced and near-ideal I have ever made. Please use it.** This PET bottle opener can also be a closer. Previously, my opener had to be turned upside down to use it as a closer. but this does not need to be turned upside down. Although it can be opened and closed firmly, it is easy to put on and take off. I solved the conflicting request. I made an opener-closer before (https://www.thingiverse.com/thing:4604278), but I had a problem with deadlocking when I applied strong force. This time I solved this problem. [idea] In order to solve the deadlock problem, the second fin layer(inner) has a floating structure so that it can rotate to avoid deadlocking. [post printing] -Spray silicone oil etc. on the part where the outer and inner are in contact with each other. Applying oil first makes it easier to insert the inner. -Push the inner into the outer to integrate it. If the inner is pushed in correctly, the inner will rotate slightly left and right. Be careful of the direction of the fins. Make sure that the outer fins and the inner fins are in opposite directions.(Please refer to the video https://youtu.be/YCaU_wa_Wo0 ) 2022/01/03(v3) Corrected the gap between the inner and outer from 0.4mm to 0.3mm. Reduced rattling. 2021/12/30(v2) Changed the holding of the top ring from contact fins (longer fins) to support fins (shorter fins). This solved a small deadlock problem when inserting the cap. In addition, I have optimized the dimensions of each part.
