12 Pound Cannon

grabcad

​I recently searched for a ship cannon to print for a fort but didn’t find any model that could be easy printed and assembled so I upgraded one from grabcad and leave the files here in case someone needs them.My model is based on < HMS Victory 12 Pound Cannon > with some changes.The size of the model is a little strange. Maybe something went wrong with import of OPs model. Original (1x) length of the cannon is ~32 mm. You will need to scale it to your size. Printing less than 4x scale would be difficult.Cannon Muzzle has some errors in it which weren’t relevant for cura slicing. Let me know if it doesn’t work for you (It is a solid body / stl mesh frankenstein).Parts: 2x - 12P_Cannon_Axle 2x - 12P_Cannon_Axle_Mount 1x - 12P_Cannon_Base 2x - 12P_Cannon_Frontaxle(1) 1x - 12P_Cannon_Frontaxle(2) 2x - 12P_Cannon_Frontwheel 1x - 12P_Cannon_Lift 1x - 12P_Cannon_Muzzle 4x - 12P_Cannon_Pins 2x - 12P_Cannon_Rearaxle(1) 1x - 12P_Cannon_Rearaxle(2) 2x - 12P_Cannon_Rearwheel 5x - 12P_Cannon_RinghookCannon Muzzle can be printet standing with 0 mm brim or raft. Allconnections are designed as press-fit connections but can also be glued.For press-fit connections I often print small parts like pins or axlestriple with +0,1mm and -0,1mm horizontal expansion (aka XY SizeCompensation) and then use the most suitable. A postprocessing tipp thatI didn’t knew for a long time: use hot air blower or lighter to get outstrings or color defects, which has helped a lot with the wood filamentin this print
