Here you go OP.

Since so many struggle with proper setup and maintenance of BB30 and PF30, an enterprising company has come up with what I believe the best solution for those in particular who aren't real keen on setting up BB/PF30 as intended...or maintaining it. Obviously the engineers at Praxis felt this pain and responded. Demand meet supply. I believe these BB's will be wildly popular. OP because the BB is an expanding collet, I also believe it will shore up any added tolerance you have if your wear is frame based version abrasion to your press in Delrin cups. $85 and includes integrated bearings and looks to be installable in 20 minutes. Shimano crank is plug and play...no spacers which are needed with traditional BB/PF30 with Shimano 24mm crank O.D. Pretty nice solution for Shimano crank lovers who have BB/PF30 framesets who don't want to mess with gluing in bearings and/or bushings.

So you have another option if you want to deviate from design intent and a lot easier for the average home mechanic or bike shop to get it right:
