I have been using it for 6 months and no issues. There is some play between the two parts so it is a bit compliant. Also it is a big print so id suggest a 0.6mm + nozzle if you have. it does take about 750g of plastic depending on settings, but I suppose you could use print blockers on your slicer to cut down on material if you want. 

I've also added a spacer, originally I was going to print this in TPU but ultimately it wasn't necessary, the juice wasn't worth the squeeze. I have included it if you want to print it from PLA to add it as a spacer and have a slightly elevated front end.
