Is there anything more gross or disturbing than bugs in your drink? I made a made a coaster to avoid this problem - not a fan of that kind of protein supplements in my diet ;) The coaster is made of 2 layers of 3mm Birch Plywood, with a hole for the straw. Afterwards painted with acrylic paint and coated with a table top varnish to protect the coaster from staining. Food grade off course. * FOR PERSONAL USE ONLY *
Purple layer is for scoring.
Cut the files according to your machine. I cut mine twice, because I only have the F1 for now!
Paint the graphic. I used thin acrylic markers like posca's but “no name” brand.
Glue the 2 wooden layers together. I used wood glue.
Make sure that the holes fit perfectly on top of each other. To be sure, that the straw fits!!
Apply the varnish on both sides and let it dry!
Let the fun begin! Cheers!
