Here in the US, 5/16" is a good substitute for 8mm threads if you have a difficult time finding them (for this project anyways). I didn't even have to resize anything in the slicer. I've had no issues on my cutter.

Thanks for such a detailed video of the assembly process! I'm going to make a cutter too. Yours is just super👍

[@Jacob-ol3zb]

I must say, you have a lot of dedication to this recycling 3d printer filament thing. It’s rather impressive. I’m curious, why do you work so hard to do all of this?

[@function3D]

I work for money

[@PakiJeel]

Thank you for the tip that solved my bearing slipping issue. I left them slightly touching and sharpened them using sandpaper of varying grits. But I have another issue, you are cutting the bottle so easily without applying downward weight. When I try cutting it, even after adding a bit of weight my bottle keeps rising in the guide and the strip width is inconsistent. Did you face a similar issue? Or is it the action of pulling that is the key.

[@function3D]

Allow the cut strip to come out horizontally from the cut therefore pull the strip by grasping it so that it comes out horizontally as well as pulling it towards you and up at an angle of 30° or more above horizontal

당신의 채널을 굉장히 자주 시청하고 있습니다. 정말 기발하고 유용한 아이디어들이 많아요. 아주 놀랍습니다. 당신에게 많은 영향을 받고 있어요. 저도 페트병 재사용을 시도해 보려고 합니다. 어제 베어링이 도착했어요. 이걸 내가 해낼 수 있을지 상당히 궁금 합니다. 만일 성공한다면 영상을 촬영해 볼게요.

Great design! When you are printing with the PET filament do you dry it before? I've been having problems with moisture causing bad layer adhesion but haven't seen anyone drying their PET bottle filament.

[@function3D]

I never dry my filaments, for me, humidity and 3D printing have no relation

[@jacobnowatzke4371]

70-75C for a few hours will do the trick. I use a large air tight tupperware bin, to which I've added a mesh container filled with silica dessicant that dries at the same time as the filament. PET is very hygroscopic- I live in a very humid climate at sea level, so I'm always fighting it. I do 170°F for about five hours after pultruding. Drying like this drastically improves my print quality.

[@function3D]

@@rickroller5742 I didn't talk about plastic not absorbing moisture, whether it does or doesn't in my experience is irrelevant to 3D printing

[@rickroller5742]

@@function3D depends on the plastic most normal ones don't absorb much

[@PakiJeel]

Excellent cutter, but I face an issue. I am using 608ZZ Bearings and it works perfectly but after sometimes the bearings slip against each other. Is that an issue that you faced?

[@function3D]

@@PakiJeel The bearings must slip against each other, they must not be forced, if you are forcing them it is because you have not sharpened them properly, watch in the second 15 of this video kzbin.info/www/bejne/mmGadJKwdrV6f9U

@@function3D Thank you for the quick reply! I Get it! Been doing it wrong! Will try loosening them up after I print a new cutter frame!

Did order your bottle cutter, and paid including shipment cost I hope it is all trustable, thanks in advance

[@function3D]

You can be sure of that

[@jayjaynet]

Should I expand the plastic bottles before slicing them?

[@function3D]

Only if the bottle has manufacturing corrugations

[@luislugo2546]

Awesome work, man!!! I managed put in the works my first "frankenstein" Petalot (It's a mess hehehe) I love the bottle cutter with bearings, it's so easy and clean cuts.Question, this cutter version with the adjustable threaded rod isn't available to print?

que buen trabajo... construyendo algunos recicladores, aca en buenos aires! :) que medida de ancho debería quedarme la cinta de PET para construir filamento?

[@function3D]

El ancho no es una preferencia si no una "obligación" dictada por el grosor de la pared de la botella function3d.xyz/faqs/?Display_FAQ=267

[@hernancurras]

@@function3D brillante... muchas gracias, no noté ese FAQ... por cierto, vi varias botellas que procesaste... paredes planas, lisas y con resultados muy consistentes, una envidia. Voy a ver como copiar la tecnica con botellas con formatos bastante mas particulares (i.e. cocacola)

[@temmietopegold]

when printing the recycled filament how strong is ti compared to PLA and PETG, i never have good interlayer adhesion

[@function3D]

Prints slow, with considerable high flow and without layer fan whenever possible

[@arturomendez7945]

Thanks for sharing. Why have you print it in PETG?

[@function3D]

It is PET not PETG, I don't see any other way to do it if not with the same filament that you do with that cutter

[@arturomendez7945]

@@function3D you mean cutter block is printed in PET itself? How many grams/meters/bottles were used?

[@function3D]

@@arturomendez7945 The nearly 50 machines and many more cutters I have printed on PET bottle filament. The cutter block takes 9 meters, 28 grams or one bottle.

Anyone has the problem that the stripes keeps on getting wider? Please help …. Thank you..

[@Serkunny]

What is the dremel that you used?

[@function3D]

A very cheap one from AliExpress

[@charyschen7856]

How to control the width of the pet strip？

[@function3D]

This is a skill that needs to be developed, observe and modify your ways of doing it, pull with the strip horizontal and upwards except for the first turn

[@user-xi8wr7zp8x]

the 608 RS bearings works for the other machine or not? and very good job bro

Yes, the 608 is the same for the filament manufacturing machine

[@function3D]

@@user-xi8wr7zp8x If they are 608zz or 608rs (zz or rs I think defines the type of seal they use) they should fit since 608 should completely define the dimensions, which are 8x22x7 mm

I have this problem it cuts the bottle, but the bottle creeps up, what can be the reason?

[@function3D]

1. bottle is not flat 2. bearing are not sharp 3. The contraption not well adjusted 4. You are not pulling upward and toward you. 5. You have not yet practiced enough to develop this skill ....
