Ống dẫn PTFE cho TPU bản ngắn hơn – Core One

I added a template for marking the hole, it's a lot of work, I recommend drilling with a 1.5mm drill and then using a 3mm drill, otherwise there is a risk of cracking the large central part, you need to drill around the circumference with a 1.5mm drill and carefully break it out, then clean the circle, the DREMEL is ideal for this, it's a bit laborious and time-consuming, but you want to do it sequentially so that the movement is smooth

Here is a list of the mods in the photo if anyone is asking :)
