I’ve always loved LEGO’s. When I found out that Louisville got a Bricks and MiniFigs (franchise) store, I had to go check it out. (Prices should be visible if you zoom in on the pictures)
Yes, they have Minifigs
Yes, they have New-In-The-Box Sets
Yes, they have Used Sets – some parts may be the wrong colors, accessories might be missing
(The price got cropped. It was $80)
They have Tubs of Loose Bulk Parts that you can buy:
I don’t see myself making any purchases there anytime soon. I have no specific projects in mind; I do have a desire to build some of the sets I’ve seen go by over the years, but it would be more cost effective for me to get an account with Pley than to actually buy the sets, I think.
Then again, for a large set, at $40/month .. suppose I do this for 3 months.. I don’t get to keep any of the sets.. $120.. Hmm. Maybe I’ll revisit that.
First, what are the actual measurements we must match? Taking multiple measurements:
- A: Diameter of a nubby: 4.92mm, 4.90, 4.89, 4.89
- B: Width and Length of a 2×2 square: 15.84mm, 15.89mm
- C: Height of a brick (ie, 3x a thin): 9.57mm, 9.59mm
Then, using NetFabb against the model (click image to for link to ThingiVerse):
- A: 4.8mm
- B: 15.8 mm
- C: 9.6 mm
My guess is that they reduced the size of the nubby because it would ooze a bit; the other two dimensions appear to be about right.
And the printed out ones:
Interesting! The nubbies are coming out a bit smaller, but the part is a bit bigger. The height is within 1 layer of where it could or should be.
Now, I want the part to print out nice and snug. Its hard to measure, but it looks like the receptor diameter for tne nubby is about 4.8mm – ie, they’re using a flex of about 0.1mm to keep things snug. So, I want to print out with a diameter above 4.8mm.
Lets try something at Flowrate 0.65, just to see what happens:
||5.02, 4.8, 4.95, 4.86
And what do you know! It fits! Pretty snug-gly!
Although, due to a hole in the original .STL file, the entire bottom of the piece got replaced with a solid face.
Mission Accomplished. 0.65 might be the answer, although it disagrees with the single-wall-thickness calibration.
While discussing the finer points of avoiding RMI stress injuries (aka carpel tunnel, but there are several others) at work, JS mentioned “if he could only tilt his trackball up by a few degrees”…
Welp, I’ve been struggling the last 2-3 weeks with all kinds of arm pain.. leading me to try all kinds of things. I liked the “tilt” idea. So I made one from Legos:
Its not the only thing I’ve made. I tried making a Droid Charging Station, but that didn’t work so well; however my Lego Monitor Tilt works pretty good:
And then.. Duct Tape. This is the original version of the “I need a handle to pull the air filter out of the furnace” thingy:
Life is good.
