I had trouble with the Sharpener moving around when I was sharpening. So I drew up some legs that use these suction cups from the Edge Pro Apex.

I also didn't like how the legs would loosen off on the bolt and not stay up when closed. So I added thumb screws, a thumb nut, and an ID 3mm x 15mm mold spring to give tension to the joint so it would not loosen off when used and would stay up when in the closed position.

I also remixed the handle and stone holder to use an ID 8mm, OD 16mm, Length 40mm,
Extra Light Yellow mold spring (for quick stone changes), an M3 bolt, and 2 cheap M3 heat-set inserts,(for finger handles on quick-change stone holder) I can't remember the size sorry, It was from a cheap Chinese set.

I also remixed the upper stone holder to use an M3 x 30mm thumbscrew (same thumbscrew as legs) and heat set insert for quick stone length adjustment.
Everything works great now! The sharpener is super sturdy when sharpening now! The quick-change stone removal and adjustment make it very easy to change stones and use stones of different lengths.

If you print please post a photo.
If you have any problems send me a message.
Step. files included if you want to change something.
PS.
The thumb nut on the leg springs are a pain to get on. You will need needle nose pliers to get them on.
