Panel Glide System for Voron 2.4 / Trident — Voron3tz

Updated 03-27-2026: Panel Lock System (Wedge-Lock V1)

Locks your panels at any height within the glide channels.

How It Works

The Lock Rail has an oblique slot at 4°. When you pinch the Lock Knob downward, the Lock Wedge travels diagonally and clamps against the panel. Pinching alone holds the panel; tightening the knob is optional for extended open positions.

3×3 mm neodymium magnets in the rail and wedge keep the wedge retracted (up) when not in use — without them, gravity pulls the wedge down and blocks the panel from sliding freely.

Operation

• Lock: Lift panel → pinch knob down → wedge clamps panel

• Secure (optional): Tighten knob clockwise for hands-free hold

• Release: Loosen knob (if tightened) → pinch knob up → magnets snap wedge back → panel slides free

One-handed operation. The two flanges on the rail body are your finger grips.

⚠ Always support the panel while adjusting. Voron 350mm panels are heavy enough to drop instantly once released. This is a positioning lock, not a brake.

Components & Hardware (per lock unit)

Assembly Tips

• You may need to trim your existing TPU rails to make room for the Lock Rail.

• Clear the slot with a drill bit or file for smooth wedge travel.

• Fits Voron 2.4 and Trident, standard 2020 extrusions. Works with Panel Glide System (model #1603376).

Note: This is a separate system from the Magnetic Panel Support (see 03-02 update below). The lever system holds panels at a fixed half-open position and covers the rail mounting holes. The Wedge-Lock locks panels at any height you choose. They can be used together.

Updated 03-09-2026: Cooling Notification

⚠ Important Note: Toolhead Cooling at High Chamber Temps

With the Panel Glide System fully installed, chamber temperatures consistently reach 55°C–57°C. At these levels, passive cooling is no longer sufficient for toolhead CANbus/USB boards like the LDO Nitehawk-SB. Without active cooling, you may experience thermal throttling, communication errors, or random disconnects during long prints.

To ensure system stability and prevent overheating of the toolhead electronics, I highly recommend installing an active cooling solution. I have designed a dedicated remix for this purpose:

👉 Noctua 4010 CW2 Cover for Nitehawk-SB (24V Always-On)

This is a remix of the original Clockwork 2 LDO Nitehawk-SB Cover with 4010 Fan Mount — big thanks to the original creator for the design!

The cover integrates a Noctua NF-A4x10 fan powered directly from the ChaoticLab TAP V2 24V lines, providing constant airflow to the PCB even at peak chamber temperatures. The fan runs continuously — no firmware configuration needed.

If you're using a different toolhead board, the same principle applies: check your board's thermal limits and add active cooling if your chamber regularly exceeds 50°C.

With active cooling installed, the Nitehawk board stays at around 63°C even at 54°C chamber temps

Updated 03-02-2026: Magnetic Panel Support System

I designed this add-on to improve both the aesthetics and functionality of the Panel Glide System. These levers mount directly into the existing holes of the Slide-In Rails on your 2020 extrusions, providing a nicer finish while adding a "service mode" to your Voron.

Key Features:

• Aesthetic Integration: Fits perfectly into the rail mounting holes, covering the exposed slots for a cleaner, more integrated look.

• Magnetic "Stay-Open" Logic: Internal magnets in both the base and the lever keep the system securely retracted when not in use, ensuring it never scratches your acrylic panels.

• Easy Access: Simply lift the panel and swing the Lock Lever underneath. The panel rests securely on it, allowing you to work inside the chamber from the front or sides without removing the glass.

• Auto-Retract: A slight lift of the panel allows the magnets to pull the levers back into their housing automatically.

• Universal Design: The levers are identical (symmetrical), so you can use the same file for both sides.

Technical Notes & Installation:

• Hardware: Requires 4x Neodymium magnets (6x3mm).

• Tool-Free Mounting: The screws thread directly into the plastic or are held by friction if your rails are printed in TPU.

• No T-Nuts Required: Testing confirms that T-Nuts behind the rail are not necessary; the friction fit is sufficient to support the panels.

Update 02-28-2026: Added top corner end caps to cover the exposed 2020 aluminum extrusions. Available in two versions: a simple push-fit cap, and an M5 version for users who prefer to tap their extrusion ends and secure the cap with an M5 screw.

Why I built this

I wanted better thermal sealing for ASA printing and quick chamber access without fighting clips. After testing multiple variants, a combination of TPU and ASA/PETG worked best. The system can be built entirely from rigid materials (ASA or PETG) for easier printing, though TPU offers better vibration damping and sealing. I don't use PLA, so I can't recommend it for this application.

How it works

Rails form 3.3mm channels — panels slide in and gravity holds them in place. Lift panels straight up for access, drop them back when done. Complete seal on all edges, no clips needed.

Panels slide out easily for cleaning, a chore made a little less tedious when access is this simple.

Key Observations

• Thermal Expansion: The "floating" design allows the acrylic panels to expand freely as the chamber heats up By not being constrained by rigid clips, the panels can move within the channels, maintaining their shape even at internal temperatures of 55C

• Odor and VOC Containment: The continuous contact along the entire edge of the panel creates a more consistent seal compared to individual clips, noticeably reducing the escape of plastic odors (VOCs) during ASA printing.

• Chamber Stability: The improved insulation helps in reaching and maintaining a stable internal temperature, which is critical for large-format ASA prints.

Choose your configuration

1. Standard (Single-Wall)

• One 3mm panel per side.

• Complete TPU or rigid material seal.

• Anti-Rattle Option: Use the Anti-Rattle Plug to hold the panel in a sealed position.

2. High Insulation (Dual-Wall)

• Two 3mm panels with a 3mm air gap.

• Likely better insulation (not personally tested).

• Setup: Inner panel (Polycarbonate recommended for heat safety) + Outer panel (Acrylic).

• Anti-Rattle Option: Use the Anti-Rattle Saddle that sits over the outer panel.

Material choice & panel sliding

TPU provides better vibration damping and thermal sealing, but has a higher friction surface — panels require a little more effort to slide in and out. If printed entirely in ASA or PETG, panels will slide more easily. Both options provide a complete seal; choose based on your priorities and printing capabilities.

Rail Types & File Selection

Several file variants are provided to match your frame and extrusion type:

• Slide-In Rails: For extrusion profiles with open ends — rails slide in axially. Fastest to install, minimal hardware. Use 1–3 M3 screws per rail to prevent sliding. Screws thread into ASA or grip TPU through friction fit.

• T-Nut Rails: For profiles with lateral access only. Requires T-nuts but straightforward to install anywhere on the frame.

• Roll-In Rails: Also for profiles with lateral access only. More difficult to install than T-Nut rails — recommended only when T-nuts are not an option.

• Press-In Seal: For the panel exit edge where rails cannot be mounted. Provides thermal sealing without a channel — simply press into place.

• Universal Solid Rail (500mm): Designed without mounting holes to ensure a clean print with TPU (no stringing, no retractions) and a 100% thermal seal. Intended for printers larger than the Prusa MK3S/MK4. Do NOT scale the Z-axis in your slicer as it will distort the cross-section. Use the Cut Tool in PrusaSlicer to trim it to your exact frame length.

Before you print — test first!

Especially if printing in TPU 95A, I strongly recommend cutting a 20–30mm section in your slicer first and printing it as a test piece. TPU prints slowly and a full-length rail is a significant time investment. Verify the channel fits your panels and the rail mounts correctly on your extrusion profile before committing to a full print.

Available lengths

Sections are provided in the lengths I use on my own Prusa MK3S: 265mm for verticals and 235mm for horizontals. The 500mm Solid Rail is provided for users with larger printers.

Technical Notes

• Panel Removal Direction: You decide — upward, toward front, or toward back. Place components accordingly.

• Press-In Seal: Install on the edge where panels exit; no channel needed, just thermal seal.

About Voron3tz

Voron3tz is a collection of open-source mods designed, printed, and tested on a Voron 2.4 350mm LDO build. Every mod comes with STEP files so you can adapt them to your own setup.

Why Voron3tz? Voron + 3D = Voroneț, a 500-year-old painted monastery in Romania with a blue pigment that somehow still hasn't faded. If the paint can survive five centuries of Bucovina weather, ASA parts can probably handle a heated chamber. Probably.

If something doesn't fit right, could work better, or you just want to share your build — drop a comment or a make. Feedback is what keeps these projects improving.
