Major Upgrade Remastered Version for 2025

Dear friends, happy Chinese National Day

My apologies, procrastination kicked in, so I haven't modified the model The previous old model has been deleted, and this is now the latest updated model

The structural design has been re-optimized, making it easier to press the button and requiring less effort

Simplified parts, making assembly more convenient and quicker, it can be fully assembled in a few minutes

The interface has been changed to a quick-tightening nut method, so even without a pneumatic connector, the PTFE tube can be securely clamped

Because this model draws inspiration from the spooler connector part designed by the great @astra32, I especially thank @astra32 for the fresh and inspiring idea

The attached installation instructions contain specific photos and both Chinese and English installation guides Just assemble according to the instructions

Below is the original introduction

A manual filament loading and unloading tool, suitable for dry boxes, preventing the need to open the dry box every time filament is loaded or unloaded Following personal preference, as always, no hardware, no pneumatic connectors, no drilling required, simply insert the 4mm PTFE tube into the guide hole and tighten the nut It is recommended to thread the filament through the model before inserting the PTFE tube and tightening the nut The PTFE tube does not need to be inserted too deeply, otherwise it will affect rotation If you feel it cannot rotate, please pull out a portion of the tube

The parts are designed with foolproof anti-misassembly interfaces, the only thing to note is the gear direction Assemble according to the assembly photos and cover image, gently pull the handle by hand, then store it inside the handwheel When inserting the filament for the first time, please straighten the end of the filament Otherwise, insertion might be a bit troublesome When unloading filament, leave a portion at the end, do not completely withdraw the filament from the device (otherwise you'll have to open the dry box lid to re-insert the filament) If you have any suggestions, please leave a comment below I am a newbie, and I will do my best to accommodate Thank you

Print in place handle is stuck. Can't free it without breaking. Tried PETG HF and PLA Basic. Any advice?

I printed again with my highest quality profile. The print in place handle works ok. Now my problem is that assembling the spring and gear stack seems impossible without breaking the spindle for the passive wheel. Maybe I am just missing something obvious, but the "assembly guide" pictures don't show anything useful. I really like the basic concept you used, but this print just doesn't work for me. :(

@user_2101863237

My apologies, the clearances may be insufficient, as different machines have varying levels of precision, even though it functions flawlessly on my equipment I will endeavor to increase the clearances slightly and revise the model accordingly Please anticipate the update, also, no supports are required If you have enabled supports, please disable them

Replying to @sqrt1787569 :

Assembly requires installing the drive wheel first, followed by the passive wheel I have photographed the steps in order, but the image sequence may be jumbled due to system formatting

The print profile is no longer public

After evaluating available models of manual filament feeders in Makerworld, I decided to give this one a try as this is compact and don't require any hardware. I would say the result is quite impressive - parts are well designed and fit nicely including ptfe tubes. Once printed and checking some of instruction photos, assembly was straight forward for me. I think some kind of holding mechanism for the the side button would be good improvement to reduce finger fatigue.

side note: I suggest you remove the first print profile if you don't want others to download since it has missing parts.

@user_2101863237

It has been redesigned, welcome to try it Thank you for providing me with more novel design inspiration, I will consider whether I can add it to make it more user-friendly

Nvmd this thing is a piece of junk

@Xento

Unfortunately, the feeder repeatedly reported filament jams. I therefore removed it again. Threading was also not easy, and the feed was not ideal.

Things I think can be improved: 1. Filament grip, not working well 2. Filament guide between in and out since most filament are bend from spool. 3. Might be best to add variant with o-ring for better grip. 4. Less door joint for easy access to fix filament path

Other Issues:It only works if there is zero resistance on the filament. if it runs through PTFE tube and a 4-1 adaptor it seems to be too much. I think it needs updating to reflect that there will always be resistance even small in any setup.

@user_2101863237

New designs are currently being tested and will be released soon please stay tuned

Great idea, stupid simple! Extremely practical for external spools. awesome idea, it works perfectly, you just need to explain it a little bit better so , this gadget allows smooth passage of the filament when the button on the side is not pushed, when you push the button on the side it grabs on to the filament and you can use the leaver on top to push the filament forward or backward. simple to operate, applies no friction to the filament when not engaged. great design!
