Print in Place Filament Guide / Idler for Direct Drive Ender and Similar
Description
NOTE: This is still being updated as I have other ideas to implement and would like to make it more modular for different filament spool locations. There are a lot of filament guides for specific situations but I couldn't find exactly what I wanted so I cobbled this together in Tinkercad. I wanted keep my dry box easy to get to, not up on the wall and be able to feed both printers from it. The current release version is print in place, no assembly at all. Just mount it it to the top of the extrusion using original t-nuts and bolts. It has shield around the top of the idler to retain the filament. I will probably remodel the project in proper software so that it's less angular.. This prints with the wheel face down, all in one piece. No support, no brim. I've run my prototypes at .2 layer height and smaller with great success. I have not tried taller layers yet. ### Current Version Print in Place v1.1 Changes - Reshaped mounting plate - Now uses single screw/nut Allows you to change angle a bit. - Countersunk area for screw head and slightly increased radius for screw Ideas - Snap on version: Snap to extrusion with no hardware needed. - Change wheel shape to allow farther off-angle feeding. ### Other Versions Print in Place v1.1 Changes * Tightened tolerances between axle/wheel and shield/wheel. * Thinned out the base plate a little, stock screws and nuts work now. Ideas * Single screw is sufficient to securely mount, will probably redesign plate * Slightly increase mounting hole size. ### Print in Place Version v1.0 - Ideas after first test * Slightly increase mounting hole size, these are exact so it can be a bit snug. * Countersink or thin out the mounting plate to allow use of original bolts. * Snap on version: Snap to extrusion with no hardware needed. ###608 Bearing Version - Work in Progress * There are some pictures uploaded side by side with PiP version. * Uses the common 608 bearing to reduce drag (skateboard/rollerskate bearings) * Easy print orientation is the goal, but may need to change for strength.. * This was actually the first one I designed but I got distracted by the print in place version. * A prototype was installed on one of my printers and worked well but needed retention.
