Heated Insert Press (4040)

I wanted to build a heated insert press but only had some 4040 extrusions kicking around. I couldn't find any premade models from it, so I borrowed ideas from multiple sources and made my own. All my M5 bolts were also 2mm short, so I found a model and printed some. The design is also for use with string/paracord rather than a piece of belt because that's just what I have on hand. For the weight I use a giant bearing, so I've added a bonus hollow sphere which can be filled with sand and blocked off with hot glue. I haven't printed or tested it though. All are designed and modified in Tinkercad, so no nice code files are available.
