A "basement" for your Kossel to give it extra breathing-room for ventilation, electronics, isolation and cable-management.
The extra height makes it a lot easier to add or replace parts. Bigger screens, additional boards, cooling fans, other position for the PSU etc.
Corner-pieces: The shape of the corner-pieces is mirroring the popular corner reinforcements of Maketo.
Dampening feet: This thing is originally designed for professional vibration dampeners (note 1) that I had in stock. But i used them for another project so i used an old project of mine (2) to create printed ones. They work great in reducing the vibration and noise. Included are three types: soft, medium and stiff. I myself use the soft ones. See printing instructions.
2020-frame-pieces (3): Of course you can use aluminum frame-pieces (2020 but also 2040). But since you have a printer you can also print them. Included is a stl of a 285mm solid frame-piece. You can print it in vase mode. Because this thing does not add to the strength of the printer you can use these. They are surprisingly strong and can be used for light loads.
To make mounting possible, the length of the pieces must between 280 and 285 mm (Kossel lineair plus). For other Kossels take the length of the original horizontal aluminium pieces and substract 15 mm (since i have no other Kossel, this is an educated guess).
Extra: two mounts for 90mm fans (4) are included. The long one is for general airflow, the short one for cooling your main board in the first place.
- Be sure the 2020-frame-pieces fits well at the corner-pieces and can slide.
- Screw the printed dampening feet to the corner-pieces with M5 screws/bolts. If you bought 25x25xm6 rubber feet, make a M6-threat first.
- Put M4-bolts and t-nuts on the corner-pieces. Use the holes closest to the feet.
- Put the corner-pieces and the 2020-frame-pieces loosely together before mounting it to the kossel.
- Mount the frame to the kossel, corner-piece by piece. By sliding the 2020-frame-pieces you can reach the bolts/screws.
- If the corner-pieces sits tight and aligned, use t-nuts and M4-bolts to secure the 2020-fram-pieces.
Happy printing :)

4a) For Anycubic Kossels: An easy way to control your extra fan is to use the gcode in your start and end code of your slicer. Connect your extra fan to the open fan1-port. Add
"M42 P7 S255 ; turn casefan on"
to your start code and the two lines
"G4 S120 ; Wait 120 seconds"
"M42 P7 S0 ; turn casefan off"
to your end code (with thanks to Master_Aar for the tip)
4b) You can also attach an extra fan with the two additional 12V-pins on the board, see picture. No firmware- or changes or startcode needed. But it will be on all the time your printer is on.
any PLA, ABS & PETG
Corner pieces: annoying enough you need supports for these pieces. Make sure the 2020 frame-pieces fits well and can slide.
2020 frame-pieces: If you print these you can use the Vase-mode in your slicer. No tops and bottom-layers needed. Use a brim for adhesion. Check if your Kossel is able to print 285mm high.
Dampening feet: Pla is possible, Petg is better (more flexible). Use concentric infill for the best result.
