Prusa INDX PTFE Tube Guide – Keeps the Tubes Away From the Moving Tools This is an upgrade for the PTFE tube holder on the Prusa INDX tool changer. On the stock setup, the PTFE tubes can hang into the path of the tool that is printing. A tube can get hit or snagged during a print, and sometimes it knocks an idle extruder off its mount, which can ruin the print or cause a crash. This guide holds all eight tubes in a fixed, spaced-out arc above the tool area, so they stay clear of the working tool no matter where it moves. Features - Eight tube holes in an arc: one per INDX tool. The arc keeps the tubes evenly spaced so they don’t tangle or rub against each other.

- Tubes stay out of the way: the tubes are held up and back, out of the path of the active tool, so it can’t catch them.

- Idle tools stay docked: with no loose tubes pulling or swinging, the parked extruders aren’t bumped off their mounts.

- Angled side walls: they brace the main panel so it stays stiff and doesn’t flex when the tubes pull on it.

- Flanged feet with screw holes: it mounts securely at both ends [using M_ screws / the existing holes on the printer].

Print settings (suggested) - Material: PETG or ASA recommended (stiffer and more heat-tolerant than PLA near the printer)

- Layer height: 0.2 mm

- Perimeters: 3 or more for strength around the tube holes

- Infill: 10–20%

- Supports: none [confirm]

Installation - Remove the stock PTFE holder [describe if needed].

- Fasten the guide using the mounting holes in the feet.

- Feed each PTFE tube through its hole, in the same order as your tools (1–8, left to right).

- Move each tool by hand through its full range to check that no tube catches.

Hardware - [Number and size of screws, e.g. 4× M3 × 8 mm]

- Hole size fits standard 4 mm OD PTFE tubing [confirm]
