Sunlu S4 Filadryer Dryer Hole Plug Bung

***NOTE*** It has been brought to my attention that some folks have printed these in PLA. PLEASE don't do this. It should be as similar to the original plug as possible which I didn't realise I had to explain, however that is why I chose TPU to print these in and I would recommend you do the same. I have however tested these using PETG & ABS and both fit perfectly, They can be pushed in and removed without issue many times without fail. Once again DO NOT USE PLA in a heated dryer that does up to 70c. As most know the outcome of that if you do.

Thank you for taking the time to read this and if you chose to print the design I hope everything works as planned for you.

Here’s a plug/bung for the Sunlu S4 Filadryer—Filament Dryer. I misplaced mine in a "safe" spot and couldn’t remember where, so I searched for designs online. I found one that looked nice, but it didn’t fit at all. So, I decided to create my own using Tinkercad.

This plug fits really well; it’s snug in the hole and also cups the black grip that releases the PTFE tube, ensuring it won’t fall out on its own. With a gentle tug, it comes out easily without any issues.

There is also no branding on this design, this is a personal preference but feel free to put whatever logo you want on your remix.
