 The model was sourced from https://www.thingiverse.com/thing:4158320 and arranged in Chitubox to add supports and slice it. One issue which was not apparent when I downloaded the STL file is that it isn't set up for any particular scale; on import it defaults to a tiny model only a few millimetres in height.

+===== 3D Model =====
+{{:blog:models:screenshot_from_2021-07-05_21-38-14.png?400|}}
+This was my first ever 3d print and I made some fairly obvious mistakes:
+   * Aligned a lot of the parts to be completely horizontal (result: resin doesn't drain properly)
+   * Used automatic supports only (result: some of the small parts are slightly warped)
+In future, it's best if parts are angled away from the build plate and lcd at anything up to 45 degrees. In addition, smaller parts do need supports!
+===== Printing =====
+{{:blog:models:img20210705235210.jpg?400|}}
+Initially everything looked good, however after starting to drain the resin vat there was a piece sitting in the bottom:
+{{:blog:models:img20210706000659.jpg?300|}}
+This appeared to be the neck connector - fortunately that one part can be printed again.
+===== Washing & Curing =====
+{{:blog:models:img20210705235558.jpg?300|}} {{:blog:models:img20210705235911.jpg?300|}}
+I did a 2 minute wash in IPA, following by a drain/dry and then a 2 minute cure cycle.
+After that process, the parts looked like this:
+ {{:blog:models:img20210706001414.jpg?300|}} {{:blog:models:img20210706001422.jpg?300|}} {{:blog:models:img20210706001440.jpg?300|}}
+===== In-Progress Images =====
+No clean-up, just snipped from the supports:

+{{:blog:models:img_2134.jpg?300|}}
+Most parts are looking pretty good - except the camera/fin (which has a warped bottom, rather than flat), and the base of the bust itself, which again is slightly bent, rather than flat. In hindsight those two parts should have been <del>affixed directly to the build plate</del> angled to allow the resin to drain, rather than <del>put on supports</del> flat which allowed it to pool on the horizontal surface.
+Some basic cleanup of the head, fin and face plate:

+The last image, above, is compared to a [[:blog:models_rx78_2_v3|1/100 scale Master Grade RX-78-2 Gundam ver 3.0]] - so you can estimate the scale of the printed bust to be //around// 1/50 to 1/60 scale.
+Mock up of the final piece, missing the neck part, of course:

+==== Re-printed part ====
+**[Update July 10th 2021]** - Reprinted the failed neck connection part, played around with the orientation in the slicing software and added some more supports, as well as recalibrated the 0-position. It printed much better this time:
