With a sigh of relief I was glad to get that last non-puzzle project out of the way so I can again let my hair down and get back to reality with another puzzle.
Some may ask "Why all these puzzles all at once?"… well it’s like dripping water... sooner or later it’ll eventually impregnate your psyche.
"3 Plates Burr"??? I don’t come up with these names… when I plagiarise from the Internet, I believe the author deserves the courtesy (even if he/she plagiarised it in turn from some other plagiarist by a different name) and I should "lemming" them.
Unlike the “traditional” burrs, this consists of 3 convoluted pieces and should only be attempted by laser lamination or build out of cubes like most sane puzzlers do… unless you’re deft with chisels and have a bucketload of different razor sharp sizes… or have/get a CNC or... more on this at a later spot.
Initially I forgot where I dug this up from,
but after putting on my deer stalkers hat and a quick suck on the pipe,
I rushed to my computer and tracked it down to this Printables link… a great let in for ("later spot") all you 3D printed printing freaks.
Winter has passed so I can’t use cold as the excuse for working from the office, however, I can fall back on the proximity to my fridge which is keeping my cask-o-vino from evaporating... my excuse for lack of workshop happy snaps.
Because of the convoluted shapes, this was a case of laser cut, 6mm MDF laminations, so the audience, apart from puzzle haters, could be further limited. However, for the sake of the poor bunnies that may get this as a gift from me, here is the splurge... though more so for the relevant solution links below, below.
Downloaded the STL file into SketchUp and it was just a case of subdividing each piece into the potential build up layers. Working on a 24mm square base (4 x 6mm MDF), designed for 4mm dowel alignment, the following model took shape,
and set up for transfer through the various software
to the laser. Pieces are butted up to minimise wastage, however, once two pieces are abutted, the overlap lines (marked in red) have to be tidied up (in CorelDraw)
to prevent duplicate cutting of the same line... which is no major issue other than extra charring and unnecessary processing.
Now I harp on about dowel alignment… it is not perfect as the 4mm holes laser cut will be 100% accurate, the 4mm dowel diameter and the 6mm MDF thickness, will depend on how much 白酒 (baijiu) the underpaid Chinese labourer imbibed in.
Consequently alignment is not always perfect and some doctoring may be required.
After the laser, these are what I have to contend with,
that need to be sanded to remove all the burn marks, which is usually done after assembly as the inside faces don’t really need the facelift… ‘cept for Superman or us boomers that bought those x-ray glasses
advertised in comics back in the 60’s… which are probably sitting on top of the Charles Atlas body building book
bought from the ad directly below/above the specs... and if you were a RF and could afford coloured comics, this would suck ya in,
Enough prattle… The 3D printable can be downloaded from the link near the front of this blog and anyone into SU can download the model from the following 3DW (or just browse it)
With my laser I always moved the pieces apart a tad like you do. Then I found the "delete duplicate cuts" button and fixed that, but then got tired of resizing all the parts to compensate for the beam width and ended up moving them apart again. 🙄
That last Atlas ad, poor "weakling" got so jacked up on the special Charles Atlas steroid gummies he now has a violent streak! 😱
Oh yeah lemmings funny little critters, hours of time wasting there too. the x ray glasses ...tick The half a man ...tick the dancing ...tick the puzzle ...tick so that's a 100% Result ... boy your good
