What is it?

It’s a riser. Just a riser. But with a massive upgrade.

If you love the simplicity of the original—giving you that crucial overhead perimeter for high-quality LED lighting to watch your Snapmaker U1 toolheads swap without building a massive full enclosure—this version is built for you.

The Just-A-Riser XL+ takes the original sleek layout and packs it with essential community-requested upgrades for ventilation, tool management, and top-cover compatibility.

What’s New in the XL+ Version?

• 💨 Multi-Sided Air Vents: Strategically placed along the front and sides to manage airflow and keep your chamber temperature stable when using a top cover.

• ⚡ Integrated MultiConnect Sockets: Built-in connector slots locatedon the front and sides. Easily snap on your favorite tool holders, camera mounts, or accessories from the MultiConnect ecosystem.

• 🔒 Perfect Alignment Holes: Features precision alignment holes on the top corners to easily lock down the official Snapmaker U1 Top Cover.

• 🔄 Universal Top Compatibility: The top geometry directly replicates the native U1 frame. It seamlessly fits the BIQU TopCap and should easily accommodate most other aftermarket or DIY lids.

Key Features Retained from XL:

• Recessed LED Track: Generous perimeter channel to flush-mount LED strips for shadow-free, crystal-clear toolchanger viewing.

• Extra Headroom: Plenty of clearance for PTFE tubes and umbilical wiring bundles to move

• Simple Install: Sits naturally on your machine without overcomplicating your setup

Print Settings: Due to some serious OCD on my part, this model takes some time to print. To speed it up, you may want to turn off Adaptive Layer Height, up the Layer Height in general, and increase the Overhangs/Bridges Speed. This profile will need some supports for those pieces with vents. Follow the guidelines below for best results:

• PLA For Support Interface - Used the defaults when choosing PLA for interface layerr, except I added 3 top and bottom Interface Layers.

•  Overhang Speeds - Slowed all by aprox 20%

• Filament Cooling - Set Max Fan Speed and Overhangs and External Bridges Fan Speed to 100%

Fitment between the bars is tight by design, once you get the bars started, you may need to gently tap them down with a rubber mallet, do so on a flat surface.

Since the vents are "Print In Place", you'll need to press in each vent opening from the outside, you should here a light pop, the the vents should be free.

If you don't use a cover and don't require vents, checkout my Just-A-Rizer XL

I will be adding videos as we go, the first is on fitment, enjoy!

If you test this with any other custom top covers, please drop a comment and let me know how it fits! Happy printing!
