Description

Tired of bumping terrain and minis around when measuring out threat ranges and movement? Look no further.

This compass lets you quickly measure out distances of 1 to 9 inches in tight spaces. In just 1 second, rotate and snap the arm into position and your compass is set. Great addition to any tabletop gaming kit like Kill Team or other battles in the 41st millennium !

Features:

1 inch increment snaps
Numbers readable when printed with multi color or single color. Your choice!
Should be accurate to approximately 0.04" (1 mm) or less. Design compensates for the shrinkage of PLA
Uses 34 grams of filament with 2 colors (or 27g if you print single color)

Tips for great results:

Important to minimize warping: Let the build plate cool naturally before removing parts.
Turn off ironing if you want a quicker print. It's on for cosmetics only.
Threaded gear bolt will hit a natural stop when it is all the way in. Stop there. Don't overtighten.
Dimensionally designed for PLA. Use other materials at your own discretion.
Supports are not needed
Little assembly video shown below
April 30 2026 update: A1 mini profiles uploaded. These profiles are for a slightly shorter compass spread over 2 plates to make it fit. It should be functionally very similar.

Happy gaming!

Mine cheats a little bit. 6 inches shows a little bit more than 6 inches

@MooseAndBolter

Sorry you're having issues. Can you estimate how far off yours is? What material did you print with? There are several things could be going on here potentially. First, the paper ruler you're comparing against is a bit short (mine is definitely not exactly 6", see picture. It's about 0.025in or 0.6mm short). Second, in my testing it was impossible to get rid of discrepancies 100%. But it was never off by more than 1mm or so (and mentioned in the description). There are a few factors that affect this such as thermal shrinkage behavior, distortion when being taken off the plate etc. but with tweaks I was seeing less than 1mm and called it "good enough", since generally this is a game of inches not mm's.

Replying to @MooseAndBolter :

I used Bambulab PLA Basic gray filament. 6" measures 6 and 1/16"

@MooseAndBolter

Replying to @Fjorden :

ok thanks for checking. Since my test prints only show half of this discrepancy, it'll be hard for me to make further adjustments or make a suggestion that'll work for everyone. One thing you can do to improve it without wasting filament is clip off a mm from the tips of the compass. It shouldn't affect functionality but would compensate a little bit.
