Mouse funnel mousetrap
After thinking a bit more about my design for a Peanut Butter Jar Mousetrap, I decided it could be even more minimal/adaptable.
This new mouse funnel mousetrap design requires four bolts, four nuts, and some kind of container with a 4cm hole in it.
Peanut butter is still a really good idea.

Shattered acrylic plastruder… Yikes! I printed up one of Zaggo’s Prinstruders – but it appears to be optimized for an early MakerBot Batch 5 with large/small dinos. If I wanted to use my printstruder I would need to pick up some of the extra parts required and essentially print up a small dino.1 However, I think I’d like to start replacing parts out of my MakerBot with printed parts so that I can keep the originals as backups. However, I have a feeling a prinstruder out of ABS is going to be much more robust/resilient than the layered acrylic plastruder. What do I need?
In addition to these parts, I’ll also need to measure my ‘bot for a small dino equivalent. Since my extruder barrel is out of commission and the plastruder is just lying on the platform, this is as good a time as any to measure it up.
A common question from some of my friends is “How noisy is the robot?” Since getting the belts tensioned pretty well and getting the stepper motors tuned up, it’s a little noisier. But, it is quieter than our dishwasher or central heating unit.
Rubber band for MakerBot noise reduction
Besides making sure the rods are oiled and bolts tightened (they get loose with all the shaking) I noticed that compressing the two sides of the Y stage helped with noise reduction. By taking a thick rubber band, stretching it, and tying a big knot in either end I can put it in the slots for the opto-endstop triggers. This has helped a little. You’ll notice I stretched them over the two bolts. This seems to also have helped just a little bit.
