Description

Hotend / ToolHead PTFE Guide v2

Don't forget to Follow!

Thank you so much for your Downloads, Like and BOOSTS!

The PTFE guide is positioned so your PTFE tube no longer rubs the top glass. The perfectly designed connector, rotates smoothly and follows the motion of your Bambu Hotend. The natural curve, without restriction to the PTFE tube helps reduce AMS Filament retraction errors.

Fast & Easy print in all materials
No supports required
Perfect smooth fit on PTFE connector
Rotates freely
Helps resolve AMS Filament Retraction problems
Prevents PTFE tube from touching glass top
Provides a natural curve to the PTFE tube

INSTALLATION:

Feed PTFE tube through the printed guide, using your other hand, push the curve in PTFE to help slide tube through the bottom of the guide.
Slide the printed guide up the PTFE, giving you more room to push PTFE tube back onto hotend. Attach PTFE tube back on the Hotend connector.
Lower Guide onto black PTFE hotend connector. Using mild force, "wiggle it, just a little bit"," at an angle, to snap the printed guide onto the black PTFE hotend connector. It takes some force.

REMOVAL:

I rotate guide so the PTFE is pointing forward, while pulling up/bending the guide forward.
Be prepared… this printed PTFE guide might break or bend at the bottom during removal, be ready to print another.

NOTE: I recommend using PETG or ABS/ASA that can handle the higher temperatures of the print chamber.

PETG

Easy & quick to print. Installing it takes a little bit of guts due to the force required, but it’s not that bad once you get over the initial fear of breaking the tool head. 😉

@K2_Kevin

A little wiggle goes a long way! Thanks for printing & rating! Enjoy!

Yes, reminiscent of the 1980s classic, lol https://youtu.be/ikYGBBULC40?t=77

ASA - 103% Scale for shrinkage factor

The guide printed great, but man I thought I was going to break something when installing it lol. No kidding when you said a little force required, but it fits tight and secure. I used 3Djake ASA with their recommended settings.

@K2_Kevin

Id print extra, when you remove it can break. In fact I designed the base to break away before it beaks the actually hotend connection.

Thanks, will do!

@user_2125754890

I was just going to ask, how do you remove it? I printed it in PETG, and not does it feel like it'll break if I try to remove it. Also, and issues with it affecting filament going in or damaging the ptfe tube?

PETG

Printed well with a few minor tweaks to the PETG profile, but unfortunately did no solve my retraction issue. I am convinced it is the spools. With or without ring adapters some spools seem to cause issues sometimes. I might have to look into a re-spooler.

@K2_Kevin

Have you tried a diff. spool of PETG? You could try changing temps as well.

@BedlamThreadz

It printed fine, just didn't solve my problem. The polymaker black PLA spools seem to be the problem. With or without ring adapters I keep getting failed to pull back from the extruder and retraction errors.

@3D_TN_

Replying to @BedlamThreadz :

is it the matte PLA? i have issues with the black pollyterra polymaker also.

@Johan501

Printed in eSun PETG. I really like it! Now it doesn't touch the top panel anymore! 😁 I only don't know how to remove it if necessary. 😅😋

The designer has replied

@K2_Kevin

Removal is tricky, id say you break it when removing. Its a balance between holding on to the coupler or falling off. I just bend forward and pop it off. So maybe printing more than one is sugested.

@Purr_geandPrint

Replying to @K2_Kevin :

Just print it in Overture Easynylon, try it, perfect material for this usage.

@ReadyShootAim

Replying to @K2_Kevin :

how do you install?

PETG

I change Star rating because after 5th atempt I figureout how to solve my problem with snaping parts (look in photo). All the time there was problem to instal this thing on extruder konin, but yesterday when I make maitenance and change extruder I unscrue this ptfe knoob and try one more time with little help of heat gun. I made bottom part softer with heatgun and put it into this knob, then form it back properly with my fingers to recve right shape with not much friction when moving round.

@K2_Kevin

sounds like the material you used is shrinking more than what I have accommodated for. I would try to scale up the print to 104-105%. shrinking is normal with abs, not as much with PETG, depends on the brand.

@psuchecki

New PETG is on the way and i’ll try reprint it with your sugestions. You are expirienced person with a lot very usefull projects and deserve to more stars ;) Thanks for hint.

@K2_Kevin add info about heat bottom part a little before instalation and this solve problems :)

ABS - 103% Scale for shrinkage factor

worked like a charm after raising the hotbed to 100°C, waited for 10', changed building plate and put glue onto the plate.

@K2_Kevin

ABS likes to warp and release from bed. Get chamber temp up and heat soak the bed for 10 minutes before (Raise bed temp to 95-100, use glue stick or nano polymer. You can do it!

@mZauchner

@K2_Kevin thanks for the support. finally worked: did all of your recommendations and changed the building plate.

@K2_Kevin

Replying to @mZauchner :

NICE! ABS can be finicky, but once you get it working well, its pretty great stuff!

@K_VAN

PLA - NOT RECOMMENDED

Wonderful! Printed in PLA for now.

@K2_Kevin

Looks great, but yeah, expect PLA to begin to warp

@K_VAN

Replying to @K2_Kevin :

Absolutely. Chamber isn't going over 36C with PLA. If i go for higher temp materials I'll definitely print one with PETG or better. Thanks again!

printed from nylon works great

Looks great, great choice of materials

PLA - NOT RECOMMENDED

I recently tested an upper tube guide. The product performs its task of preventing tube twisting, but during installation, I found that the material used, PLA, proved fragile and broke easily. I would recommend considering the use of a more durable material like PETG to ensure greater long-term durability.

@K2_Kevin

Id recomend ABS, it can get hot up there!

@3Dreamworld

Replying to @K2_Kevin :

I had thought that PLA wouldn't be suitable, given the high temperatures there. Indeed, I removed it immediately. Thank you anyway for the advice. 💪🏼

PETG

Nice print, though not sure where the defects comes from. I print on an X1C, and use BL PETG Basic White / BL filament profile. I only have this filament, so cannot test with other brand, or roll just now. I believe I did do filament calibration when I opened the roll, and drying. Maybe need to try it again, before printing a spare. If I do - I will of course edit this, if it turns out to be a filament issue. With that said, the defects do not hinder its function + can be cleaned up partly.

@K2_Kevin

I’d say slow down the print. using white filaments all flavors can be an issue unless calibrated. white filament is very finicky due to its properties/composition.

@Amn2009

only unwrapped the white PETG, but have a black one as well. Using Bambu default/auto selected print settings for their filament, but sure slow down and/or try black filament I can try. All white Bambu PLA/PLA Tough prints great though at default settings, but did hear PETG can be more tricky.
