Description
There is no point in telling about the usefulness of PET tapes in everyday life. Egorov’s lawyer testified and proved the usefulness of bottle cutters. The design of his version of this product is magnificent, but not perfect. In this regard, there are many variations. Including using 3D printing.
And here the fun begins. 3D printed bottle cutters. The bottom of the bottle. To solve this problem is to do everything possible to make it compact and open for use and manufacture.
The models available in the 3D Today and Thingiverse website in general geometry were analyzed and made us on clerical knives, turning the latter into a bottle cutter!
Thus, task No. 1 is completed. No. 3 and 4, too.
Everything is simple! But really not rosy. did not want to work right away of this design. How easy and convenient. It didn’t work the first time. It did not work from the second. And even from the third and fourth. Try to play with the angles of entry and exit from the wall of the bottle cutter. Increased / decreased the height and width of bottle stabilizing collars. Add a hole for the M5 hairpin, similar to the original design. Does not work!
Bad options:
And it does not work as:
pressure is required on the bottle, pressing it to the bottle cutter
stabilization of its position relative to the bottle cutter (otherwise the tape width is not stable)
a sharp (fresh, without chips and burrs) blade because there is no knife slope in the design in view of the cut
The solution is simple. It is necessary to lay a bottle around the city. In the forest, it can be a bitch. It was recorded in a reel with plastic. In the country, you can add a stopper to the bench with a nail through a pre-prepared hole slightly larger than the diameter of the nail. Or insert a bottle into a pipe. There are many options for fixing without using a vice and tricky fastening. THOSE. and the second task to recognize completed.
Vkontakte https://vk.com/mnogo3d (subscribe, like, order) because here we have not learned how to join the video. There is also an archive with models for printing.
The video shows the version of MAXI. The rest are its derivatives. MINI is a MAXI without pin holes.
SuperMINI and MINISuperSmall have not been tested. May not work because a remote wall appeared in them. There is given the opposite angle, but still.
The hole is not just for convenience. It is recommended to put on the strap. Eliminate the likelihood that the scissors will push.
Use it!
Sincerely, Much 3D (3D printing in Ryazan)
PS. Layer 0.2 is quite enough. We recommend printing. To facilitate removal, a hole was made in the 'bottom'. Filling we did 50-70%. Duplicate ABS model. intermediate were also from PLA.
