help with editing a model

[Cyber-Mav]

anyone on here able to modify this stl so it goes from this:

to something like this:

this filament holder doesnt clear the filament feeder so need the extra distance.

STL file is here: https://www.thingiverse.com/thing:4756703

trying this in fusion 360 but got no clue if it can be done.

 

[Cyber-Mav]

Got this sorted in the end

 

[Cyber-Mav]

looks like you are using tinker cad. I could teach you how to do this in tinker in probably sub 60 seconds. If you throw me the stl I could do you a little video ahh fusion, to be fair you can do this in any tool quite easily and i didnt see the bottom bit of txt. Ill grab the stl and do a little tutorial at some point over the next few days

That would be excellent. Thanks for this vince i cant believe you can do it in sub 60 seconds lol.

 

[Cyber-Mav]

@Vince any update on this chap?

 

[Cyber-Mav]

@Vince thanks for that vid, explained a lot to me, i was able to mod the design using your video and tinkercad seems to be excellent and simple to use thanks to how you explained it.

i made some mods however im thinking of modding the pole that sticks out to be able to stick some bearings onto it to allow much smoother movement of the filament roll. any ideas on how to go abouts it?

 

[Cyber-Mav]

some good design ideas there. wondering if i should get an external filament box that also dry's filament?

 

[Cyber-Mav]

Thats good stuff, your video shows me how to make holes too, use hollowing cylinder set size to 6mm and use it as a drill bit to get required depth and then group everything and it makes the hole.
Understanding this more now.

 

[Cyber-Mav]

Thats awsome. With some good measuring its possible to make a lot of fixes for stuff. Also very impressed with the strength of pla when its around 3mm thick

 

[Cyber-Mav]

Ahh I made one with a bearing in before second I can look through my models

See the end of the spool holder, is it possible to slice that end stop off and make it a screw on type? That way i can alter its diameter and slap on a row of bearings and screw on the end stop to stop bearings falling out. Hehehe

 

[Cyber-Mav]

Ahh just noticed that thread insert sort of thing. Can it do metric sizes like m6 etc?

 

[Cyber-Mav]

It can, id have to have a look but I made a load of stuff with m* bolts.

fantastic, i can imagine people 3d printing wheel nuts and bolts for cars lol.

 

[Cyber-Mav]

Iv noticed that in tinkercad making thread holes in a shape results in size issues with the threads. Doing a metric m8 hole with threads the hole was so small only a m6 screw would fit in it properly.
Trying again now with thread and hole size for m6, m8 and m10 to see how it ends up.
Why this happens?

 

[Cyber-Mav]

hmm so m8 hole should be 8.4mm diameter? the hole i ended up with was only able to fit in a m6 bolt.
im trying a few more test prints overnight

 

[Cyber-Mav]

Measure it print a cylinder with a known inner diameter of say 10mm then measure the inside. It will likely be 9.x mm. After that compensate the model and reprint. You can do this with a couple of quick 5 min prints.

ahh good idea, at the moment iv got these 3 being printed:

3 cylinders with m6, m8 and m10 size. will see how they turn out.

Did this today, printed 3 cylinders with holes inside, a 6mm, 8mm and 10mm.
These printed out close to perfect in size so looks like there is an issue with printing out threadded holes which end up almost 2mm smaller than they are supposed to be.

 

[Cyber-Mav]

Well that makes sense, if thread hole size is constantly off by x amount then i guess compensating for it is the way to go. Will do few more test cylinders with threads around 1.5mm oversized and see how snug the screws are.
Good stuff though these 3d printers, the possibilities are endless

 

[Cyber-Mav]

im using tinkercad.
in tinkercad an m6 hole prints out to a proper 6mm hole but add threads making its an m6 threaded hole and for some odd reason it shrinks the hole by 1.5-2mm.

 

[Cyber-Mav]

fusion is big boys toys, our man here is just starting out his journey Eventually he will find something that isn't simple in the likes of tinker and end up being forced but thought edge him in gently

haha, just starting out on my journey. will need to try some software like autocad or fusion360 and see if threads is more accurate there.

 

[Cyber-Mav]

Hmm anyone done print in place of a nut and bolt together?

 

[Cyber-Mav]

Thats too much work to tap and die etc i may as well get a lathe machine and use aluminium billets to do the job. Lol

I did a benchy which seems to be decent for a mini mico budget printer
