pedal ideas for 3d printer

[deadastronaut]

here's the general idea..

[JohnForeman]

Turns out my first pedal 3D print was for a spacer.

[deadastronaut]

Come on john, that's too easy...

sorted it though..

[Johan]

How about badges?  Like a crest, to glue on to your builds. ..like the"supplier to the royal Court"badge on abu garcia fishing reels. ..

lol i know.  i thought the same thing when i was trying to figure out what to use for a spacer..  then it was like DUH!

i'll have some 'really hard' stuff posted up tonight..

what if you printed an external dress-nut for that dc socket, w/ maybe "don't be stupid, it's center positive" engraved in, and then use the original supplied nut as the internal spacer/tightener?

great idea but the threads printed by these things are not very strong.  So it would hold very well.

it's been a while since i've tuned my printer and it looks like it needs it.  As you can see the A and O's didn't print correctly.   It may be better to try a two color print.  But with a single color printer, that can be a pain in the behind..

Those look great!

Cool...so you need a stencil font then, to get the tags for certain letters...

that's what i'm looking for, a stencil font.  i'll have to google that.  thanks

[deadastronaut]

dafont.com  is pretty good.

[JohnForeman]

ok.  did two more prints with a different font and different thickness.

The top row looks like the font that will work out best.
Also, the top row is 1mm thick.  the bottom row is 2mm thick.

I think i can get the prints just a little better after i adjust the temps a little.

[JohnForeman]

whats the rotation angle of the pots we use?  I could also print these out with graduation marks from min to max.  just need to know the total angle.

[duck_arse]

that's asking for trouble. there would be 3 different angles of rotation in my pot drawer. you would need to specify "these labels suit 270 degree rotation pots", and "... 300 degree ..." then we can all look up the manuf data for what is in our drawers/hands.

happy new stuff.

yes, old thread, but it seems the right place.

one of you 3d printer people - would it be possible to print a spline-shaft pot despliner? I've been tryiing, again, to fit a set-screw knob to a splined pot, with assorted adaptors trying to stop the knob nosing (it leans), and haven't yet come up with a satisfactory solution. solution? I can't even understand the mechanics of the problem.

so, the despliner - it would have a central "stick" to fill the shaft-split, and inverse splines to fill the splines, and the top/capping-end would be flat and squared off outer, and would fill the shaft-end bevel. the outer diameter would obviously be clearance for a set-screw knob.

possible? printable? worth thinking about?

I've been 3D printing enclosures to test drill locations. Hammond's website has the 3D files for all of their boxes that you can edit in 123D then spit out the stl for printing.

How about this ?

"Maybe" but probably not, there may not be enough room unless the hole for the knob is a good amount bigger than the splined shaft. I do use my 3D printer for a few pedal build things...

1. Various jigs/spacers for setting/gluing.
2. Jack isolation inserts.
3. A PCB holder that slides in and holds the PCB which means I no longer have to JB weld standoffs in.

I tried printing knobs for awhile but the fit and finish at that small tolerance gets a little iffy - I may have to revisit actually.

Beyond pedals, my 3D printer is one of the best purchases I have ever made; they are great for printing items that don't exist or you don't have.

Made this on the 3D printer a while back, a replacement Mu-Tron knob, that have gone the way of the Dodo. 

3D file can be downloaded at Thingiverse, if you just happen to have a Mu-Tron with a missing knob?

Knobs would be nice to make on a resin/SLA printer, because they are perfect at small, detailed objects.  I did some experimenting with some other knobs and could model in a slot underneath for a metal nut, that a set screw can tighten in, so you aren't just threading through the plastic.
