Makerbot Replicator 1 Filament Guide

This is an improved filament guide tube holder & guide for the Makerbot Replicator Dual. The original guide tubes snap to rear panel of the printer, not aligned with the spool at all. Most of the filament guides I found here put too much of a bend on the filament leading to breaks during print jobs.

This version snaps into the original filament guide tube holders, so no hardware is required. The tube is moved to the centre of a normal 1kg spool and the cone shaped opening makes it easy to load filament into the tube and prevents sharp bends in the filament.

Based the design on the concept of the FlashForge Creator PRO Filament tube holder by Paul4x4Design, but recreated it from scratch in Fusion 360.
