Multicolor Triquetra Drawer knob to use with M4 bolt

Description

This new design solves two problems from my last design: * It's setup to use an M4 nut so the bolt isn't going directly into plastic which makes it much sturdier * It no longer requires supports to print * The handle is thinner which is more ascetically pleasing IMO Note that I'm using an M4 nut because our Ikea furniture uses M4 bolts for the doors and drawers. To assemble after printing all pieces: * Use a 3mm drill bit to drill out the little bit of material in the bottom piece that blocks the hole. This material is necessary to allow the print to succeed without supports. * Put an M4 nut in the bottom piece. You may have to put a bolt in it and push a bit to get it started * Put the bottom insert into the bottom AFTER putting the nut in, this keeps the nut near the back of the handle. Note that if you have Elephants foot on your print it's going to be a pain here, so you might have to cut some of the insert off and the nut will be a little loose which isn't the end of the world but is a little annoying when attaching the handles. * Optional: Cut some pieces of paper clip (or other 1mm rods) to just under 1cm. Insert these in the 4 little holes in the bottom piece and dry fit the top onto the bottom to make sure the paper clp pieces line up. You may have to use a 1mm drill bit to widen the holes if your 3d printer as imprecise as mine. If you skip this step it will be more difficult to get the top and bottom exactly aligned. * Use super glue to attach the top and bottom pieces together with the pieces of paper clip in place to keep them aligned (or align them without the paper clip pieces, good luck!). * Use super glue to attach the decorative pieces to the handle. I recommend dipping the decorations in super glue then putting them in the handle, ideally with tweezers because supper glue likes sticking to skin more than plastic. * Attach your handle to your door or drawer and feel mighty pleased with yourself.
