This Thingie is a Double Remix!
I wanted a peanut butter jar lid for K-Cup compost collector and have adapted two other things, 1st) the lid by 3Dmigos "Screw Lid for Nutella Jar" (1001973) with 2nd) the base of dbibeau's "Coffee Monsta! Eats the used coffee grounds in your spent k-cups!" (711329).
Print both and then bolt the Coffee Monsta (or REV C TOP) to the modified Nutella lid with 3 #8 x 1/2 or 5/8 machine screws. You now have a K-Cup Compost Collector to screw onto that peanut butter jar you have because you don't have a mason jar to collect the K-Cup grounds.
Both items will take about 3 hours to print. Coffee Monsta is thing 711329, search on that. A year from now the top will degrade and break down and a new one can be bolted onto to peanut butter jar lid.
I buy one pound Smucker's organic creamy, a standard size glass jar; composting collecting is a good repurposing of a peanut butter glass jar! In the photo you see a green "fill your own" K-cup, if the scraper is ever redesigned (it was, see update below) then the new one is bolted onto the lid, no need to print both parts. Hmmm, what other tops can now fit on a peanut butter jar?
UPDATE 6/25: the photo features a modified TOP to print, added a 30 mm diameter flat surface at the top to scrape the inside corners of the K-Cup. Tap the cup until most coffee has fallen out and then twist back and forth to "scrape" the inside corners of the cup!
Again, I was able to create this quickly from the work of 3Dmigos and dbibeau. Thanks very much for posting your work to Thingiverse! Credit others!
