S1 Max Riser for Ace2Pro – Printable Heavy Duty Base

This structural riser is specifically designed for the Anycubic Kobra S1 Max Combo and fully compatible with the Ace2Pro and AcePro filament units. Update 28.02.2026 I made some minor adjustments. Update 01.03.2026, PEI Magnetic Plate Support Added "This version now includes integrated support for magnetic PEI build plates. The riser geometry has been updated to allow secure mounting of magnetic sheets or rigid magnetic PEI plates without compromising structural rigidity. Guidance channels and flat seating surfaces were refined to ensure proper alignment and stable contact. No changes were made to the core load-bearing structure. Strength and stability remain unchanged. This upgrade increases usability and flexibility for users running multiple PEI plates or fast-swap printing workflows." Update April, 2026 : The turqoise parts on the top of the riser has been updated to be used for AcePro and Ace2Pro. Download the Kobra S1 Max - Ace2Pro Riser.3mf from the link. The goal is simple: increase clearance, improve structural rigidity and create a clean integration platform for Ace2Pro without modifying your printer frame. If you are looking for: • Extra under-printer storage space • Improved structural stability • A cleaner Ace2Pro setup This upgrade was designed exactly for that. Design Philosophy Instead of adding random spacers, this riser distributes load evenly across both side frames and uses reinforced cross beams to reduce torsion under dynamic movement. The geometry keeps alignment consistent with factory tolerances.
