Pty Maker Cable Chain Holder

thingiverse

I want to build a 4 x 8 cnc router for cutting out designs in wood for a friend, as well as probably one for my maker space, and depending on interest might actually try to spin it into a bussiness that will manufacture low cost cnc routers for schools and the like in the Republic of Panama. The purchase of the machine might involve putting it together as well as some hands on work. Hopefully this will be done through our "currently being born" makerspace. As you might imagine price/hands-on learning/inhouse production are a fundamental part of this pitch, as well as struggling to save a buck when possible,. For example the metal structure of the machine will be plasma cut out of 1/8" steel and a couple parts such as the limit switch holders willl be 3dprinted. Looking at cable carrier chains I saw the opportunity to not only save a couple bucks, add these to the inhouse manufacture list and as a bonus personalize the links.as well. There are a few other things we had to consider as well. Printing roughly 4 meters of chain one link at a time was out of the question. So we had to design a pattern that would allow us to print as much as possible per iteration. In this case a little over 60 cms per job. (a little under 2 feet) The size should be as compact as possible (read fast) , and as light as possible (read cheap), while still maintaining enough structure to handle the cable load. The part should also be printed in under 16 hours so that it would print during the off office hours, 4 iterations of this design were made, each a little lighter, smaller and (hopefully) cooler looking. As the size shrunk, and to save space on the bed a couple touches were done to the hinge system to allow the hinge to be printed in place, and then snapped free. The final product is ideal for a large cnc with a thick router cable, 3 limit switches, one Nema 32, and 2 Nema 24 stepper motors, with enough space left over for another thick cable and probably the cables from another sensor or two.These cable holders are probably NOT for 3d printers.. A set of 5 is roundabouts 47mmx40mm200mm long As with any Remix it would have been loads more work without the work of Landru and Rotoscan both of whom did an awesome job. Thank you to both Printed 4 trays already.. Y and z axis are done. Carefully take off bed and and gently snap... They will assemble through the top as the bale part has a taper on the side away from the pty maker logo first layer speed must be 5mm or 10mm/sec MAX.. otherwise your parts might fail... 10% infill.. 2 layers 0.2 mm thickness...and level your print bed...
