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.

| Frame | The largest part, with the anchor’s sloped bar engraved Crimpdeq Spark and the cord tube | |
| Ring wall | Cradle for the 38 mm roller | |
| Middle wall | Cradle for the 40 mm roller | |
