Aleene's glue bottle cap

We go through a lot of glue in the engineering lab. When it's crunch time and the presentation is due soon, the caps from the glue bottles are often a casualty of the struggle. It's no good if they turn up weeks later, so make a few replacements to have on hand!

I printed these from PLA, standing on their heads to avoid support, with a little brim. I get a nice positive fit on the bottle--you can pick up the bottle by the cap without pulling it off.
