Summary

Get a little Cretaceous assistance with those hard to reach itches.
Modular poles allow you to get just the right length.

Instructions

Printed in PLA at 0.2 mm resolution. No rafts, no supports.
Print time: 4hr for the skull, 4hr for a set of two poles.

The Angled skull attachment (V2) was used for the make pictured here. The teeth come out wicked sharp, so file down to your desired level of scratch.

Assembly:
Proceed very cautiously with the screw attachment of the pieces. (I was forceful with the first set of poles that I printed and ended up snapping off one of the connectors)
Carefully align the pieces to get the threads to start. When resistance is met, screw back and forth slowly until the parts work through the rough parts. Occasionally, take the pieces apart completely and wipe off any plastic residue from the threads. In the end, the poles fit together nice and flush and feel very solid.

A "test print" of the poles is provided with short fragments so you can check your settings before committing to printing the large ones. As a bonus, the short piece can be used as an end-cap for the scratcher pole.
