Aluminum Extrusion 3D Printer Carriage

thingiverse

This is a carriage engineered to glide smoothly on 25mm 80-20 Aluminum extrusion, commonly utilized in the construction of 3D Printers. The model employs Openbuilds Carriage wheels and 10mm spacers, but includes all necessary files for production. To achieve optimal results, it is highly recommended to utilize Openbuilds wheels instead of printing them. The carriages also feature set screw adjustment to tighten the wheel against the extrusion, a crucial aspect for tuning. The part was originally designed to serve as the primary source of linear movement for my Delta 3D Printer and has functioned flawlessly in every instance so far. Links are provided below for the entire printer. Here is a short teaser video of the Delta 3D Printer - https://www.youtube.com/watch?v=EX2o5emcHi4 http://www.thingiverse.com/thing:1266969 UPDATE 1-23-17 Hello everyone, After many months and thousands of hours of design time, I am nearly ready to release the final version of my consumer-grade Dimension 3 MultiMachine Delta 3D Printer.

Post-Printing Cleaning up the prints After the prints are completed, simply remove all supports and assemble it. Gathering Materials To build the carriages, you will require a few hardware components. 3 50mm M5 bolts with matching Nyloc nuts 6 Printed 10mm Spacers 3 Openbuilds Solid V Wheel Kit (http://openbuildspartstore.com/solid-v-wheel-kit/) 2 25mm M3 Bolts with matching nut for delta arm connection 2 1" long 6/32" screw (for wheel tightening) Assembly First, add the set screw in the side of the plates to tighten the wheel. Then slide one of the 50mm M5 bolts through the back plate. Next, slide on a 10mil spacer then an Openbuilds wheel, followed by another 10mil spacer. Finally, slide on the front plate and bolt it together. Repeat this process for the other two wheels. Mounting to the extrusion After mounting two wheels, connect it to the printer by attaching the third wheel and spacers. Once it is securely fastened and sitting on the extrusion, you can tighten the set screws to bring the third wheel closer to the extrusion, thus tightening up the entire system. Delta Setup Once mounted, use the 2 25mm M3 screws to attach the arms of the delta printer to the carriage plates. There are also two slots perfectly suited for a G2 2mm pitch 6mm wide belt, which is depicted above. I utilized Traxxas ball joints for my arms, so that is what I designed this to use; however, you can adapt it to work with various arm designs.
