The arch 3572 may possible match the curvatures of the sloped bricks 3573, 7249, 50950, and 24309.
We need to confirm these matches using physical parts.

Does anyone have two or more of these parts?

A. Does the curvature of 3573/7249 match the curvature of 50950/24309?
B. Does the curvature of 3573/7249 match the curvature of 3572?
C. Does the curvature of 50950/24309 match the curvature of 3572?

I know what BI data claims, but now we need physical confirmation.

Plate Special Round 4 x 4 with Melting Drops on Sides (Part 65702) - It features prominently on the feet of #40806 Gingerbread AT-AT Walker.

Related part 65700 is already available.

Where is the official list of reasons for hold-voting a part?

Some of the border vertices in the toucan subfiles have slightly different rounding of the fourth decimal, which causes white dots to appear along the seams between subparts. The shape is free-form so there is no primitive that would cause it. It can be hard to detect, but it seems reviewers have anyway certified it.

What is the current policy? Are fourth decimal gaps allowed or not?

If allowed, what is the largest gap that can be accepted in a free-form shape?

Is there a way to search for parts/subparts that have had a hold vote for more than 3 months?

Can the results be filtered to include only such part authors that haven't logged on in the last 3 months?

In recent days, Philippe Hurbain has added three of the four new Bluetooth-based LEGO Science parts to the parts Tracker.  I'm personally excited to see LEGO finally moving to USB-C for charging their devices, as well as curious to see how well the device-to-device Bluetooth connectivity works in practice.

Assuming that these devices continue to connect with Host PC and with each other using the LEGO Wireless Protocol - it might be possible to control them using a Spike Hub, or even a City hub running PyBrick firmware.  (If anyone has any info on the protocols used or compatibility with other Powered Up hubs, let me know)

In any event, one of the parts is still not on the tracker, and I would like to include all four of the new parts in my LEGO Parts Guide.  (I believeive the guide will be especially useful to educators.)

Missing Part: 115901 (Remote Control, Science)


Thanks again for the tremendous throughput of new parts in recent months!

There are a number of wheels with an outer diameter of around 30mm, but they are very inconsistently described as 30mm or 30.4mm across different websites.  I noticed that LDraw is the most consistent here, using 30 (mm) for all four of these parts.  (Within MLCad they appear to be exactly the same width.)

1. Are they actually the same size, or are they actually measurably different?
2. Even if they are ever-so-slightly different, is 0.4mm so small that almost nobody cares?
3. Does LDraw prefer technically accurate measurements, or is it generally preferred to nudge measurements ever-so-slightly to make the system work better together?

I would like to make my part naming both technically correct and consistent.

Hi,

Does anyone have a good photo of these two drawings?

Can anyone point me to the specifications/rules for obsoleted parts? (It might be easy pickings to get off the tracker...)

Since I am not great at 3D modelling, I still wanted to give back to the community, I decided to order a 3D scanner so some of the older parts can be scanned since there is quite a lot missing from 2000 - 2020 from when there were no 3D models available. Some of the very old stuff was also hand measured so I dunno if those will want replacing since it depends how often anyone even uses those old parts really.

The scanner I will be getting is the Creality Raptor Pro.

So is there any particular preference of things that people would like scanned to start with?

If I scan the parts would someone be willing to get them ready so they can be added to the tracker?

Reducing the meshes to some kind of sensible size should be something I can do.
