TIP #002 for 3d printing: the acetone pen (and a DIY alternative!)

Amazing 3D Printing helpers: in this video I suggest the use of an acetone pen for gluing parts and small repairs (like, correcting a small delamination).

There is a product on the market exactly for that, from Filabot. You can buy it here: https://www.filabot.com/products/abssmootingpens

Or, you can follow the recipe on this video and make your own replacement! Note: the replacement does not have a retractable tip, nor did I want it to have.
