8,8 cm Sprgr. Patr. L/4,5 (Tiger, Flak 18/36 projectile)

thingiverse

here you'll find a 88mm Tiger I or Falk 18/36 projectile with shell and some pictures with more information about the interior components. there are one-piece models for the projectile and the shell as wall as a hollowed projectile and a separated model for the projectile and the shell (each 3 pcs. in total) - for people (like me) with limited print volume. I stumbled across two very good models for the projectile: https://www.thingiverse.com/thing:5173935 and https://www.thingiverse.com/thing:3198221 which will both fit in my uploaded shell I would highly recommend using one of these two models because these are so much better than mine. Also print "Tiger_I_Shell_Casing_3o3.STL" first to check the diameter of the shell and then adapt it to whatever projectile you want to fit in. Then print the rest of the shell with the same scale (all 3 parts already have 0,2mm clearance between each part). Thing 5173935 might be a little tough to get in the shell because the intersecting diameter is 87,1mm on both models - so you might have to print the casing with 101% This model originates from the following link https://grabcad.com/library/tiger-i-88mm-ammunition-1 but the dimensions were off (I thought the dimensions were inch but the whole projectile would be too big) so I adapted and uploaded it here.
