I have an STL of a Trigger Kicker I am adapting to an Extar 9mm blowback. I cut my bolt back to far now I need to modify a printed TK to see if I can make it work again. Delima- looking at the TK from the side, the arm that sticks up needs to be wider by a few mm, next I need to shorten the base by the same amount to keep the overall base length the same, and the distance from the tail to the trigger pin hole the same. I have read online tutorials but apparently either I, or they aren't very smart as I can't seem to make it work. I have cut, even moved the parts but they all show up as one part in the same 'box' I need to modify them then merge them back together. Help a moran please. ETA: I 'kinda' did it. I cut through the tip and extended the rear/tail by 3mm, but inm retrospect I also added to the area that slides under the safety. I made a second cut behind the hole and simply slid that part over the other part shortening the toal by 3mm. I'm sure there is a setting to spread them apart, add 3mm fill, then merge, and then the same but subtract 3mm. |

I agree, slicer is not the ultimate tool but I was hoping for a quick and dirty adjustment, I already have a working knowledge of Slicer and have zero idea how to work any one of the other programs, or even which is good for me, a meduim level printer but a zero level designer. I was able to cut, stretch on the X and Y axis, merge and print which accomplished my needs for this object. |

Make a few trinkets. Get comfortable. Then get Fusion or Solidworks. Fusion is also free, SW is $25\yr. The skills in one largely apply to the others, its just learning nuances of where tools are and how sketch relations work. CAD is not hard. The vast majority of designs can be boiled down to four basic operations: Extrude, Revolve, Sweep, Loft. And you can either add or subtract with each. Yes there is more but honestly just understanding those four key concepts will get you 90% there, and frankly 100% there on simpler designs. Then its just keeping the end in mind when designing for FDM. Many people dont and its a silly oversight. |
