John, for now I just cut a strip of kitchen towel and attach it inside the mask with double sided tape. What I want to do is have a formed fit rubber insert that will give a good seal. Now if I put my hand over the front opening and try to breath, it is quite forced so the seal is really pretty good...

I use Simpify 3D on a MakerGear M2 printer. I now use a hair band through the side holes and loop them. Then I take a head band and cut it and connect it to the loops with a clasp I made. Really comfortable. Let me know if you want images of final product.

I have been using another design also by a Dentist: https://firedbycorona.com This mask takes 3.5 hours to print and I have been using ESun PetG. The fit is great. I just have to sand a little on the cheek for a great fit. For a filter, I used a 3M filter by Filtrete: Advanced Allergen, Bacteria & V...

Your problem sounds similar to the one I just had. I measured the outside temp with a multimeter and got around 220 instead of the 250 reported. I had a clicking sound which I thought was the gear not able to push the filiment through the nozzle (V4) because the temp was too low. To make a long stor...

All fixed!!! Problem was the pinion gear was stripped on the extruder motor. Replacement gear $5.00 from Makergear. Life is good again

I have tried everything. I used guitar wire to pass through the hot end. Used the cleaning filiment from ESun and tried PLA filiment. Some would extrude a little then stop with the filiment drive clicking. Per Josh I measured the thermistor temp in the hot end and it is at least 25 * degrees cooler ...

That's what I thought so had both loosened and tighter it but it made no difference unless there is some trick to it. The gear imprint seems the same regardless of tension.

Hi Tim, Thanks for you comments. I found out the replacement board had a blown fuse and that is why it stopped working. Replaced it with the original and now it is connected. I believe you are right on the money and it is not the board. What is happening is when the PetG(right again) is threaded int...

Hi All, I am hoping the forum can point me in the right direction. I have had the M2 for over a year with no problems. Recently the extruder clogged so I figured now is the time to upgrade to the V4. Ordered the kit and worked great for a few weeks. Then at the end of a print I got a birds nest. The...

I was wondering if the temp needed to be higher. What temp for the white petG is everyone using and how high can I safety go with the stock VB3.
