Heat insert press

hello everyone , before all, Iam new in 3D .. and I seen lot off presses here and seem to me to much complicated, prints with suports etc .. I did try to make siply almost no support easy machine . I used screws M5 hex head and mother , rubber bend and thats practicaly all of other material then print. The top arm can be extended just siple lose mother , slide in different position . Also I thinking, about higher material where i can put this press, then siply just print one more pice, slide in place and its done. In folder you can find some pics how to assembly , I have no idea how to make assembly plan, so hope you will underestand the system . any question , just ask :-) Material : screws M5 x 30 5pcs mother M5 1pc HOT mother (thread)M5 4pcs rubber band printed from PLA , 15% infil tough enought update: I find one part was wrong.. uploaded new one
