Mosaic Spool Holder Roller Brackets for Palette2

thingiverse

I was looking for a way to make the Mosaic spool holder that ships with the Palette2 (Pro) more sturdy, so I designed these spool holder brackets. The brackets I made are two halves of a whole, and this design allows them to be adjusted to fit any size filament spool. This means they can be spread apart or pushed together to accommodate different-sized spools. So far, I haven't encountered a spool that doesn't work with these brackets, except for ZYLtech, but only because the inner hole of the ZYLtech spool isn't solid. However, it still works fine and holds the bearings in place. I made these brackets to use the supplied rods from Mosaic to ride on. The bottom of the brackets sit on two of the rods, and the third rod goes through the top center of the bracket to hold the bearings in place (along with the pegs). The bearings I used are 6001ZZ because I needed the ID to be larger than the size of the rods (which is approximately 10mm), and these bearings have a 12mm ID. Because of the difference in diameters between the bearings and brackets, I made pegs that fit snugly into the bracket and around the rods and inside of the bearings. To assemble the brackets, you'll need to center the pegs into the bearings and then push the bearing (with pegs) into the bracket. The pegs are quite thin, so it's best to print them with a layer height of 0.08mm. This setting should make the pegs strong enough to hold up to inserting into the bracket but flexible enough to slip into the bracket with little force. I've also included some spacers that help hold the brackets in place and keep the three rods together, making it easier to load the spools. They also prevent the brackets from sliding around. Since I used the supplied rods from Mosaic for the brackets to ride on, I had to purchase 7/16" dowels from my local hardware store to use in the bottom corners where the original rods were to be used. The dowels are a bit tight but with minimal effort they'll squeeze into place and help hold everything steady. Finally, I made some end brackets that fit over the top of the supplied end pieces from Mosaic to help keep the rods in place. They're also a snug fit but work quite well. You'll need two brackets per spool, one peg per bracket (but the STL file actually contains two pegs), as many spacers as you want - I use one at each end and between each spool for a total of five, and two end brackets. And, of course, one bearing per bracket. I hope you find these brackets as useful as I have. It's taken me several months to develop them, with many iterations before settling on the final design.
