How to smooth 3d pen projects without burn marks 

You are so welcome.

Here is this particular one from Amazon: www.amazon.com/Wall-Lenk-LTR100-Temperature-Regulaor/dp/B000ZHH9CU However it needs to work with the electrical parameters in your area. The one I have is for the USA standards. So research it before you get one depending on where you live.

Glad it was helpful! That's the point.

You are welcome. Glad it was helpful!

Here is the link to the wood-burning tool I use. Just supervise him at least initially. You can't get too hurt with the pen but you can with this thing. www.amazon.com/Walnut-Hollow-Versa-Temp-Temperature-Woodburning/dp/B005P1TRAS/ref=sr_1_2?keywords=walnut+hollow+wood+burning+tool+set&qid=1639617730&sr=8-2 As for the other things. My pen holder is made from a cutlery tray with clips. I have a bamboo one but I have been looking at getting a metal one. Something like this: www.amazon.com/Honey-Can-Do-KCH-02163-7-Compartment-Expandable-Organizer/dp/B007B8RKZW/ref=sr_1_2?crid=97ALO5LJ68QB&keywords=wire%2Bmesh%2Bcutlery%2Borganizer&qid=1639618272&sprefix=wire%2Bmesh%2Bcutlkery%2Caps%2C164&sr=8-2&th=1 2" Clips: www.amazon.com/Wideskall-Metal-Spring-Clamps-Rubber/dp/B01D3XNL3S/ref=sr_1_2?crid=25RFZG0KDRWRB&keywords=squeeze%2Bclips%2Bmetal&qid=1639618691&sprefix=squeze%2Bclips%2Caps%2C170&sr=8-2&th=1 The metal tray for the hot tools is actually a drip tray from my old toaster oven but you can look around at garage sales and thrift stores for something similar. Hope he has fun with it. It's a great creative tool. Let me know if you need to know more.

Should be OK I think. To be sure, check the melting temperature recommendation for your pen and for TPU and see if they match.

and whatever you get make sure it works with the electrical standards in your area. This works in the USA.
