CSM colorwork yarn mast

If you are planning for colorwork, then this yarn mast is a possible choice. It is mounted to the same post mounts as the ribber on the camshell and will turn around the center of CSM while you are knitting. You need the camshell with side-mount ribber posts to use this attachment. The cone holder is optimized for Royal-compatible cones. If you want a custom mast foot… Generally speaking, this mast should be usable on any CSM, 3d printed or not. Only the mast foot has to be modified, I guess. If you want me to modify the mast foot according to your CSM, I need detailed pictures, measurements and such, so that I can add a different foot for your machine. See last picture for details. ------------------------------ EDIT 09/01/26: Thanks to wonderful NuttyNewfie we now have a mast foot that fits an old Creelman Money Maker (see photo) with a cylinder diameter of 130cm. You just need the standard main M4 nut for the mast rod. EDIT 29/01/25: Yarn mast top, both yarn arms and brakes have been changed slightly to be a bit stronger overall. There have been some reports of broken arms and the linkage between them and the yarn top. Besides that I recommend printing all parts at least with 4 perimeters (better 6) and maybe the arms in PETG or ABS for better strength, though it should work with PLA with the current changes, too. I removed the yarn arm variants and cleaned up the files, as the angled one is the only one supported from now on. EDIT 01/03/24: Thanks to wonderful Joann Grubb we now have a mast foot that fits the TRU-KNIT CSM by Jamie Mayfield (see photo). You need two M3 screws/nuts for stabilization additionally to the main M4 nut for the mast rod. EDIT 16/1/24: I added a slightly modified yarn arm and weights in a separate folder. The yarn arm here is angled outside at its end to give a little more clearance for the weight. Choose the one you like the most. ------------------------------ Additional parts 8mm linear rod (mine is about 450 mm tall, choose whatever length you like, but I think everything starting with 450mm is ok) M4 screw 16mm (3x) M4 nut (3x) M3 screw 20mm (2x, yarn brake) M3 screw 16mm (2x, yarn arm) BBs, 4.5mm (weights) split rings (2x, weights) See CAD picture on how things go together. Regarding printing Position and orient the parts, so that you minimize support, especially the path where the yarn will go throught, or you will have to sand everything smooth. I recommend printing min. 4 perimeters, better 6 - infill is not that important, especially for yarn top and arms the yarn arms standing upright with tree support, block support at ends, see picture the yarn brake on its nose (where the hook is) without any support Regarding how accurate your printer is, you may have to postprocess aka sand the loops where the yarn will be guided through to be totally smooth and without any residue from printing. If you want to print the weights… For adding BBs to the mast weights, add a print pause at layer 139, fill them with BBs and resume print. Hints on usage I noticed that the yarn can sometimes slip out of the front eyelet when the springs are engaged. This depends a bit on overall mast height and the angle at which the yarn comes down to the cylinder. I usually use a little clip to close the slit where the yarn is fed into the eyelet and that fixes it - take a close look at the first picture and you can see it. This is a first attempt for a colorwork yarn mast. As I am clearly not experienced enough in colorwork per se so that I could easily see what could be designed better, I appreciate every comment to improve the design!
