Anyone have a working +Printrbot Smalls with the X upgrade (heated bed) they want

Anyone have a working +Printrbot Smalls with the X upgrade (heated bed) they want to post a picture of? I’m kind of clued out which way the heater should be oriented and I can’t find an AutoDesk drawing or assembly video that shows the larger heated bed.

(Also, anyone redesigned a better bearing holder that utilizes 4 bearings on the sled, and not just 3? In addition to a bad bearing, I’ve got a lot of wobble/play on the bed)

Also wondering what to do with (where to put and in what orientation) the 2 pieces of kapton tape. I think one might hold the thermistor onto the bed? and the other is the print surface? (except that the advertised print size is 8x6" while the larger piece of tape is only 8x4")
