I cant believe anyone thought this was a good solution. Heated threaded inserts are certainly a better idea but maybe Ratrig didnt want to commit their customers to the extra expense and complexity (we've all got a soldering iron right) but even a 2 printed part solution would have been miles better
You want to blow onto the heat brake. @sort_care (HudsonJoe) explains perfect how to identify which way the fan should blow. They should also have an arrow on one of the 4 sides (shame on you Sunon). @outofmarbles You could run the fan backwards like that but it would be incredibly inefficient...and noisy
Sand down the belt grabber blocks so they can slide in and out easily. They are belt tensions secured with a nyloc nuts so there is no reason for them to be an interference fit. In fact since they are tensions they should be able to slide easily
As Denis said, before inserting captive nuts, insert a long bolt right though the other way (pulling is easier), put the nut on a few turns and then pull the bolt back out which will pull the nut into place and then just unscrew the bolt and youre done. occasionally you might need a wiggle or to pull with pliers if its an 'interference fit' but this will get the nuts seated perfectly every time
