Ultimate Jig Saw Handle (remix)

I found that the squared cavity for storing extra blades was problematic while printing without supports. And who wants to clear out supports from an inner cavity. So, I made the inner cavity round so that there will be less issues while printing and not using supports. Can also print this standing up now, and the roof to that inner cavity is also rounded now.
Changes were made to the Handle only. All else is as was created by original source. I just put them here for ease of download.
