So I’m a beekeeper and we have to continuously adapt our tools to change and predators. For the fight against asian hornets, the 3D community has been really helpfull and most of the stuff can be printed at home with a small 3D printer.
However, for other stuff, such as mechanical treatments against Varroa (a nasty parasite responsible for a lot of diseases and death in bee populations), usually you can open your wallet and pay an excessive amount. Because the alternative is death and being a menace for other beekeepers and solitary bees.
There is for exemple a little cage that is usually used to rear queens. One fellow misprinted it, and has noticed that it blocks the development of the laid eggs into larvae (he left 7mm oh developpment height instead of 8mm). This doesn’t harm the queen or colony, and blocks reproduction of the parasites. After 28 days, there are no more larvae in the hive, all the parasites are exposed, and we can treat once the population kill off the nasty buggers. It is also an efficient way to sample parasites for the development of varroa-resistant lineages of bees (because we need to infest those with the parasite and then check if it is resistant or not).
Of course, that little cage that was misprinted is now under a patent, and is sold way to expensively for what it is (10 bucks, it’s not food-grade certified and the lock breaks way to easily). I do not mind paying for somebody’s work, and fair is fair, but slapping a patent on a item that exists since decades because you slightly modified it and selling it expensively while manufacturing it on the other side of the world is a little too much for my liking. I know it’s how the world works, but that doesn’t mean that I have to roll over.
Anyway, I’ve got some bought cages, and the patent. How would I go to make a STL file to print it afterwards? It’s made of a box with the hexagonal frames and some dead space for the queen, a lid to allow workers to move and a little lock. 3D Scanner? Drawing it from zero on FreeCAD with the patent and the cage next to me? Praying to Chtuluh to send me magically the file with a carrier pigeon? Or am I forced to go looking at an far-eastern webshop with a bad carbon footprint, where they sell it for 3 bucks a piece?
Drop me a message, i could design that in creo and send you any format you like. Looks like 15 minutes of work, and I love bees 😊
Yo could you upload it online for people to use. Thanks
I will do that, once OP contacts me and gives me some measurements.
Hey! I managed to draw a little bit and to solve the cage and cover. The only issue is with the little hinge, but nothing impossible to solve. If you want to, you can always correct my messy stuff if you see improvements ! https://www.thingiverse.com/thing:6557850
Are there existing models for the old design available? ‘Cuz then you could just make the modification you described to the STL.
No existing model, but it wasn’t that hard to replicate at the end
Looks like it should be simple to make in most CAD programs, personally I’d use fusion360 or openSCAD since that’s what I’m used to.
I don’t really know what the state of the art in 3D scanners is, but my guess is you’d get a cleaner STL file (less complex, less weird artifacts of scanning) from making the design yourself in a CAD program.
Yeah dont bother with 3D scanning for that model
Can you post a picture or a link to the cage you’re talking about? I bet you this would be done in 10 minutes in tinkercad
Edit: just saw the imgur link, that doesn’t look terribly complicated to make from scratch.
Took me a little more (the bottom of the cells are difficlt to draw and there aren’t a lot of files with the right bottom), but at least now I’m not scared to solve some stupid issues that always frustrate me by drawing and printing easy solutions!
Hi, if the difference is really just 1mm in height, wouldn’t it be possible to just lay a 1mm high piece of plastic in an existing cage? Fasten it with glue if needed.
Hope this isn’t off topic, feel free to downvote if it is. You just made me think about an idea of 3d printing directly in beeswax. Is there a market for that? I don’t know about beekeeping gadgets. I know foundation wax is just pressed in a mold, but a beeswax cage can’t hold a bee for very long, so maybe it’s a dumb idea.
Hi, from my experience watching beekeeper videos on YouTube - that queens/bee cage is made of plastic or similar not beeswax. Wax would melt too easily and does not have the mechanical strength to stop a bee from breaking out. As for 3D printing wax - it should be possible by just lowering the temperature of the 3D printer (if you can somehow modify the supply), and then you should be able to print what you want - candles come to mind.
Hey! You are both right! Queen and bee cages are made of plastic or sometimes wood and metal mesh. But having protective cells can be useful. If you add a queen-cell in a colony a few days before birth, that queen will almost always be accepted. In case of mated queens, their pheromones are strong enough that they will be often (but less probable depending of the season and presence of young larvae) accepted. Usually we put mated queens in a cage with some sugar so that the bees eat trough it, giving time to the queen to disperse her pheromones. Virgin queens however have the lowest acceptance rate, and it is sometimes better to re-encage them in a (now plastic) cell with a wax cover so that she will be born again. For the foundations, it is a little more difficult than just pressing at the moment, but the size of most of frame-standards would impose the use of huge machines. But it would be less human-energy consuming than the actual method
A few hours in blender will generate an equivalent.
Honestly I just started designing stuff myself in tinkercad, before eventually moving to blender.
This was fascinating to read. I have no idea, but i hope the piracy community can figure it out and help save bees :3
Is the original 8mm version still not under patent? You could just take that one and cut 1mm of height off of it.
Hi all! Thanks for all the replies ! I played a little bit with Tinkercad and we’re close enough. The only part needing perfection is the little lock (le opening piece needs manual help to open), but that’s the same thing for the original one. An other solution is indeed passing through a chinese marketplace if the wait is not long enough and the CO2 impact is not important for you. The printer was a little difficult to have it printed, and I had to print it on the side.
I’ve uploaded it on Thingiverse : https://www.thingiverse.com/thing:6557850
I know this link existst, but sometimes when it’s treatment season those are out of stock, or take forever to arrive. I can print 4 in a few hours, so it can always help to print one at home. Also, I’m not sure, but I think the ecological impact is bigger if it comes through the Aliexpress expedition than through 3D printing using filaments from Vietnam. But the link is valid, and and is way better to order there price-wise than to order it here!
