Tx22 printed mags

So I've been playing with 3d printing mags for the tx22 because my free rebate mags from Taurus have been "awaiting shipment" for a month now. The best set up I found is the 16 round mag and throwing one of the +4 base pads (both found on thingiverse) on it but the followers all come up short and fail to activate slide lock. I've played with resizing them in a few directions and shaving off material from both the feed lips and the follower itself and can't seem to get it to sit all the way up. Anyone have any experience with these or advice of what to try? I have no modeling chops so I wouldn't know what to do to fix the model.
