Tank Accessory Pack no 2: Americans
This pack contains a number of updates and add-ons for m_bergman's excellent 1/200 scale tanks (http://www.thingiverse.com/thing:232248, http://www.thingiverse.com/thing:310476, and http://www.thingiverse.com/thing:539511). As with accessory pack 1, these are focused on printing at 1/100 scale with ease of printing (especially reduced support cleanup) and better detail. I've also added some goodies to allow printing of variant models as follows:
cckw (aka deuce and a half) truck - I converted the original design to include closed cab and covered bed, as I thought this was more the iconic version of the truck. I also split the bottom chassis out, so the two pieces print more easily, and the all of m_bergman chassis detail looks great. I also made separate wheels with tread detail.
Common parts - I separated out the .50 cal mg. This way the mg prints cleanly. I drill a small hole the bottom of the .50 cal and glue it to a post on the turret (sometimes I made the post out of plastic rod. I've also had some success using a pair of 1mm x 2mm magnets to hold the gun on. The commander figures are just a scaled down version of Thing 557037 available at http://www.thingiverse.com/thing:557037
One and a half ton truck - I separated wheels and undercarriage as with the cckw
Jeep - separate body and detailed wheels. I also made a gun mount version for the .50 cal
m2a1 and m3a1 half tracks - Include separate detailed tracks and wheels
m4a1 - many combinations including open hatch "commander" version, as well as bocage cutter hulls for both 75 and 76mm. I also made a dd tank, but it should be considered experimental - I've printed the it and it works but it needs some cleanup. Note that there are some newer versions of the turrets where I've tapered the barrel;
it looks good at 1/100 scale. Note all use the sherman tracks
m4a3 - combinations include 105mm and commander, and an Easy Eight hull with separated hvss tracks. Use the bergman 76mm turret for the easy eight.
m5a1 Stuart - This includes commander/non-commander, and bocage cutter hulls. I also thinned down the gun barrel in the turrets. This ended up one of the best-looking models in the bunch.
m7 Priest - I separated the hull and gun, to limit the amount of support material cleanup. Use the sherman tracks
m8 Armored Car - The greyhound. separate wheels with detail added, undercarriage split, thinned barrel.
M8 Scott HMC - Use the m5a1 tracks. I modified the gun barrel to be rounder and have a hint of a hollowed barrel
m10 Tank Destroyer - Separate hull and tracks, tapered rounded gun barrel.
m18 Hellcat - separate tracks, tapered barrel
- m20 - I separated wheels and hull, and printed the gunner separate. Use the .50 cal mg
Printing notes in a .txt in the zip file
Generally print hulls with supports, turrets with support and raft, and tracks/wheels can go with or without support. I usually use 0.1mm and PLA, though other settings can work
Cleanup: I use a sharp woodworking chisel for most of the cleanup, followed by sanding sticks. Take
care to remove the lip created where hulls contact your build surface; it will prevent your tracks/wheels
from gluing in straight and secure.
See the photo of the m8 for the use of magnets for the .50 cal mgs. It's looking like a good solution
to the broken machine gun problem
Gluing: I use gel CA glue
Painting: Primed in grey, undercoated in US Army drab, blackwashed, drybrushed a couple of times, gloss varnished, decaled, gloss varnished again, brown washed, matte varnished, weathered, and finally dull coated.
I used blender's boolean operations to separate pieces. I used the array and curve modifiers to create an object that can be "subtracted" from the solid treads/wheels to add track detail.
