Modular Ender 3 Filament Guide

thingiverse

Modular filament guide for an Ender 3. Bolts onto the spool holder plate. This setup requires you to have a variety of M3 hardware depending on configuration, and should you use PTFE tubing as lining like I did, you're going to want said pieces of tubing and one M4x12 bolt per liner. The parts may need some explaining - for that, the text files are present. But basically most parts have modifiers. Sunk/Sink = Parts have a recess for a 5.5mm cheese head. I'm assuming that's standard head size for M3's. It's what I got, anyway. Clearance = The bolt through holes have a clearance fit - they should slide right through. Nut = There's a recess for a M3 nut. I think mine are 5mm? Thread = The holes are small enough that a M3 bolt will cut threads into it. So you don't need a nut. Thin = It's 4mm instead of 6mm, because I didn't have long enough bolts for my final setup. Rotate = Instead of having three distinct holes, it has a bigger hole that allows using the ClampPlates for a custom angle joint. Note that I've had best experiences setting the angle fixed by printing on a glass bed and setting up two bedside surfaces against one another - the smoothness makes them stick together REAL good. Spacer = Thicker plate to go across the spool holder plate from the inside. Through = 4mm plate with clearance holes to be mounted underneath a Top plate. Top = 6mm plate with recesses for M3 bolts. Reinforce = An arm intended to be mounted in FRONT of a plate, to double up on the rigidity of the arm. Useful for the first guide, setup tends to flex otherwise. Intended to be used with a Top plate, but will fit anyway if you use Flat and a thicker Through plate. Flat = Currently, the reinforced arm has sockets that fit in the sinkholes of a Top plate. If you're going to be using a Through plate, the Flat removes those sockets.
