Hello, I designed a mighty heat insert press, there are many designs live but this design is all printable on A1 mini and doesn't include any complex hardware. It's compact and stable.

Assembly is fairly easy with just a small detail. There's a hole on the shaft of the hand wheel and on the gear. You just need to insert a pin or a piece of filament there to keep them synchronized. 

There's an additional bottom compartment for storing your bits and pieces. 

Only requires M6 or ¼ bolt (25-30mm length) and an M6 nut for the assembly and an optional rubber band or suitable spring..
