Parts

How to put together a printed Spark grip. The pictures show the right-hand grip at the model’s defaults; a left-hand grip is its mirror image and goes together the same way.

You need the 14 printed parts, a cord for the anchor, a mallet or hammer with a small wood block, and optionally an inert lubricant such as Super Lube.

The ring, middle and index walls look alike: label them as you take them off the plate (the slicer’s object list names every part). Each wall’s cradle matches its roller.
