‘Trading Card Dispenser’ control box - servo switch controlled

October 1st

Back at the beginning of the month, before I fitted the remote control, inside my transmitter, I had thought about utilising the servo activated switch module, that I’d bought for the GOUD-4 droid.

So I combined the bracket I’d designed up for it with a new saved version of the control box base.

wrong RC servo switch.....

Some other modifications were needed to accommodate the alternative model timer circuit board I’d bought, as well as doing away with the lid's side clips and replacing them with a brass knurled threaded insert. The lid section needed alterations to and the design of the slots was simplified. I did away with the LED ‘on’ indicator as it wasn’t necessary.

Have been test printing both in work and at home. It was good to use my printer that’s not been used in over a year. Dusted off the Tevo Tarantula Pro (Orange), fired it up, first print, perfectly just like always.

Probably should mention using online program, Astroprints for creating the gcode for printing on the Tevo.

UPDATE October 2024:

The RC servo switch seen in the above images was the wrong one!

I've updated with the correct RC switch, so for more I'll be posting up a new correct set of parts & 3D printable components. 

R5’s Bad Motivator : reincarnation (Part 3)

As mentioned in my previous post, Monday saw me start on drawing/creating the ‘Bad Motivator’ as i saw it in the movie, screen grab. See below.

There are some features that I can now see that I didn’t before, and these have already been captured by other already created designs. So these I’ve incorporated into my design as I believe them to be correct in my opinion, and scaled the other parts to better match (again, how I saw/see them) into my design.

The first design I wasn’t 100% happy with so altered it for version 2. I was going to print each component separately, but couldn’t be bothered lol, plus the combined part’s secured the motivator better as one. This would be great as a resin printed piece, but for now I’ll have to make do with my printer lol.

3D coloured rendering of new motivator.

I uploaded the file to Astroprint so that I could print out at home on my Tevo Tarantula. The printer is running already, hopefully this will be done by the morning.

(Astroprint is a free online program to convert stl files into gcodes for your chosen 3D printer)

13hrs later…… the print came out great 👍🏽

Wasn’t happy about the size/scale though so going to edit and reprint.

Remote control/wristband 'communication devices'

Finished these both off with Velcro attached to the straps.

Half hours worth of stitching by hand, sees both surfaces of the Velcro attached.

Am really please with how these have turned out. Of course how useful they actually are will be found out when they are actually used :D

Software used:

AutoCAD Inventor 3D [work program]

Astroprint [online slicing program]

*** UPDATE OCTOBER 2022 ***

The stl files are now available free on my Prusa account.

A Life-form scanner for R4-D4 - Part 9

 Yesterday I drew up a support bracket that the Life-form scanner [LFS] unit would attach to.

I printed of a test version to check it would all fit. Well it did in the CAD assembly and it did in the dome.

The only thing that has been bugging me is the amount the LFS protrudes out of the dome. I wanted it to go higher.

So after looking at where I could save and therefore increase the height, I removed the coiled wire and lower greeblie from the mast. This meant I could increase protrusion by 40mm out of the dome. This meant the support bracket had to be made shorter, no problem, 20mins on CAD/Astroprint to reduce and produce a gcode file for the Tevo to get printing. Sound impressive, but it’s not lol :D

The two aluminium tubes needed to be carefully cut shorter to allow the full assembly to actually fit inside the dome. The tubes wall thickness meant holding it in the vice was tricky, but not impossible. The upper ‘collar’ I’d removed earlier, I placed on the end of the second tube to act as a stop. I’ll either cut this shorter or draw up and print another part.

To gain some extra ‘height’ I cut away some of the upper servo holder that guided the main tube. This allowed the lower servos connection to the tube a bit more clearance [see pic below]

This will be redesigned in on the next update.

The two parts connect well. I’ll be putting brass threaded inserts into the support bracket to secure them together. The bracket has two holes to secure it to the wood frame.
