Railcore Vibration Damper Mount

thingiverse

These are parts allowing you to mount your railcore X/Y motors with vibration damper. This makes the printer significantly quieter. As an added bonus, drive pulleys are placed in double shear, taking all side force off the motor shaft. I printed all the parts out of CF PETG; only the Pulley Support required support material. A PDF in the files lists the full BOM needed to build one; you will need to double this for X and Y. I know it works with the 713 halo, and I assume it works with aluminum motor mounts. Probably does not work with printed motor mounts. Some notes on purchased parts: Motor Damper: Available pretty much everywhere. I used these: https://www.amazon.com/gp/product/B07GWN6V89/ref=ppx_yo_dt_b_asin_image_o00_s00?ie=UTF8&psc=1 5mm coupler: Again, you can probably get these from anywhere; I used these. https://www.amazon.com/gp/product/B07XXB1WR2/ref=ppx_yo_dt_b_asin_image_o09_s00?ie=UTF8&psc=1 GT2 Pulley: I am using the Gates one that Filastruder is selling. 5mm Shaft: Had some issues with this; the first ones I ordered were horribly tapered. I ended up with these and they worked okay. Cut down to 65mm long. https://www.amazon.com/gp/product/B076XW73Q7/ref=ppx_yo_dt_b_asin_image_o07_s00?ie=UTF8&psc=1 625ZZ bearings can be sourced anywhere. https://www.amazon.com/gp/product/B01LWMT95S/ref=ppx_yo_dt_b_asin_image_o08_s00?ie=UTF8&psc=1 You will also want a bag of these to dial in your pulley height. https://www.amazon.com/gp/product/B0036R4R9Y/ref=ppx_yo_dt_b_asin_image_o09_s01?ie=UTF8&psc=1 As far as stepper motors go, you should be fine with just about anything. I know it works with both the E3D and LDO motors that came with the kits. Anything with a shaft in the 20-27mm long range should be fine.
