The purpose of this system was to remove the factory top-mounted spool holder with a side-fed system, so that a dry box or other side spool setup can be used. I have a Sidewinder X1 printer, but it works with standard v-slot gantry tubing (6 mm opening).

Key features: • Utilizes the factory filament break sensor, but changes the mount to reduce drag • Minimizes drag throughout the whole setup • Keeps the system very low profile • No modification of the X1 is required • Prints can be mirrored for right hand or left hand feed direction • Optimized parts kept as small as possible, and design for 3D printing (minimal supports) • Can be used with other printers that use the same gantry support beams

Bearings and tubing: (my links go through "Smile" program for donation to charities. If you don't want to go that way, in the link type "www" instead of "smile"): Bearings: These have thick grease in them, so use a little WD-40 to make them spin easily If you'll use a lot of these, then buy the 100 pack. (I use them for all kinds of projects, like filament dry boxes.) https://smile.amazon.com/gp/product/B07JB2Y4H3/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 If not, buy the 20 pack https://smile.amazon.com/gp/product/B07C6FL8TW/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 PTFE Teflon tubing: 1.75 https://smile.amazon.com/Teflon-Bowden-Filament-2-0mm-4-0mm/dp/B01CUPV9KC/ref=sr_1_4?
