Small printeable Inkle loom for weaving belts, bands, etc. The loom attaches to most tabletops with the two C-clamps. Alternatively there are slots in the clamp holders to thread a strap or velcro band so that you can strap the loom to your leg in order to use it anywhere...In a park, on the subway, etc.
With a jigsaw you could make this out of plywood and some dowels in about 15 minutes - but no, you are a Plastic Person and you are going to print it! You need seven tubes, two clamps (if you are using them) and one of everything else. I believe I used M3x10 bolts for the body, M4x45s to attach the tubes and tensioner and M5x50s for the clamps. The table clamps go through the slots provided and point away from the loom so that the business side of the loom will face you when it is clamped to a table. If you don't know how to warp and use an Inkle loom, there are lots of resources online. I've attached a Rhino screenshot to show the warping pattern.
