This model is a riser for the Anycubic Kobra S1.

The Kobra S1 Classic riser works for both the Ace-pro and the Ace-pro 2.

NEW: 2026-6-15 Added a universal version of the Kobra S1 Classic riser which works with both the Ace pro 1 and the Ace pro 2. Please download and use the files "Kobra S1 Classic Universal". The only change is the removal of the pads and modification of the top profile on the rear right, rear left, middle right and middle left- no need to reprint the rest. I have left all other versions there for backward compatibility. I have verified the design but have not test printed it. If there are any issues please let me know so that I may correct them. Thank you.

NEW: Added an Ace-pro V1 to Ace-pro V2 adapter. Free to download on Makeronline: https://www.makeronline.com/en/model/Ace-pro%201%20to%20Ace-pro%202%20Adapter/279394.html?trackModuleType=10

The riser features (some of the add-on features are available as free to download models on Makeronline):

• Two large storage drawers with customizable compartments.
• Side mounted external spool and mount;
• Corner filament guide. It helps prevents jams and tangles by routing the filament around corner and connects to the rear Bowden tube;
• Integrated build plate holder that can hold multiple build plates;
• Tool tray add on
• Lid riser;
• LED mounting bars and LED rear housing;
• Customizable sign (a blank sign STL is included)
• Much more.

Specifications:

The riser adds 15 cm (6 inches) of height to the Kobra S1 and Ace pro combo.
Total height with Ace pro opened is approximately 107 cm (42 inches). The Kobra S1 riser requires about 2kg of filament for the base unit including drawers and inlays.

Options

The part "Front left (no sign)" is available as an STL (no with the print profile). Use this part if you do not wish to use the sign.

Instructions

All parts are snap fit and require no external hardware. Glue is optional.

See the instruction gif in the model's description photos. I also uploaded a zip file with all the instruction photos.

NOTE: If you want to use the WLED controller (see description and link below) then you will need to print the parts as modified by Hasan for the WLED controller (see the zip file "Modifications for WLED control unit)

3d printing

A print profile is included for the S1 (name: Anycubic - Riser main components v2.3mf). I highly recommend you use the print profile as all the support is painted and the parts are correctly positioned.

I HAVE PAINTED SUPPORT ON ALL PARTS ON THE INCLUDED PRINT PROFILE. SLICE IT USING TREE MANUAL.

I have printed each part and tested everything. Tolerances are tight where they have to be. If you are having issues with your printer, your filament or adhesion I suggest you ask for help on Facebook or a forum as I cannot help you there.
