This design was inspired by stew675's riser for the Plus 4.

I made this riser cause i wasn't happy with the current riser of the SV08 on printable. There is venting on the top u can open or close with a grid contained inside. 

Compared to stew riser its very much cheaper, it lack led strip holder and other fancy detail. for now its just a simple riser.

Printing : 

Obviously if you want to heat up a bit the chamber i don't recommand PLA. To prevent warping and optimize the part life i recommend to use at least petg-cf/petg-gf. 

Also since i copied stew clips i would recommand users to use stew simple calibration cross model to dial in the Shrinkage XY percentages for your filament.  to quote stew : 

"Performing this step will ensure that the assembled riser will fit snugly into the printer, and that the top glass lid will also fit snugly into the riser.  Over the full size of the assembled part, I was able to arrive at an assembled part dimensional accuracy that was precisely in line with the 0.6mm cold-clearances for the riser's edges within the printer's frame.

This step is especially critical for high-shrinkage filaments like ABS or ASA where over a ~460mm distance the dimensions can easily be thrown off enough such that the glass panel will no longer fit properly within the assembled riser.

Additionally, be sure to calibrate your filament for the correct flow-rate multiplier and pressure-advance.  Both of these calibrations will be important for the best fitment of the jigsaw dovetails when assembling the riser.

The jigsaw joints were designed with a 0.16mm clearances between the contours of two mating parts.  I found that when pressure advance and flow rates are dialed in correctly, this results in parts that will slide together smoothly with minimal effort/friction, while still providing a snug fit.  If your joints are too loose or too tight, then chances are high that you need to calibrate your flow rates and pressure advance values for your filament."
