3D printing with a prusa

[laurent_muchacho]

to be able to evaluate the cheapest option we need to make a list of how many are interested I agree

If you give me a bit of time I will refine the BOM this weekend in regard to all the screws and exact length or threaded rods and smooth rod. I almost got the post ready.

First we need to see if there is enough 6mm PLY in makerspace for cutting the frame

The price for the threaded rod and screws were taken from this site https://www.orbitalfasteners.co.uk/ so far it’s the cheapest source I’ve found but the delivery is £7 + This is really where we should put our focus into first.

The challenging part are the smooth rod normally hardened chrome 8mm are used with LM8UU Linear Ball Bearing but I’ve been testing copper bushing and they work great on softer rod I’ve asked previously if someone could pickup some for me from a shop in hatfield

Favor: anyone around hatfield

I was wondering if maybe a member commute or work near Hatfield and could pickup an order for me there. I’m doing some research for a project and got a small order of a few rod and tube but delivery is like £7 or £8. Details below Many thanks I’ll owe you one https://www.aluminiumwarehouse.co.uk/ Aluminium Warehouse Welham Green Hatfield Hertfordshire AL9 7HF <img src="https://maps.googleapis.com/maps/api/staticmap?maptype=roadmap&amp;center=51.736584,-0.216936&amp;zoom=17&…

next would be stepper motor

Most other items are delivery free

@Esther_Gladstone and I would also be interested in joining in if this has legs

[RobertL]

I’m interested.

Toolstation has stainless threaded rod.

Ebay has almost anything

Is the prusa i3 considered better than anet a8?
It actually looks very similar

[peter_hellyer (Pete Hellyer)]

the anet a8, as far as I know is a clone of the prusa i3 - Quality may vary in how accurate a clone it is.

[mikekelly]

Yep, I’m in!

First we need to see if there is enough 6mm PLY in makerspace for cutting the frame

maybe if enough of us are onboard, we could ger onboard with @RichM and use his metal cutting contacts to do this in something steely and sexy?

[Jonathan (Louis)]

I can get anything cut on a water jet or laser anytime it’s needed… keep me posted…

[RobertL]

How much is suitable sheet metal? As the offer from @Jonathan seems too good to pass up

[peter_hellyer (Pete Hellyer)]

presumably 6mm alu. would be ideal, but depends whether welds are needed. @laurent_muchacho?

[laurent_muchacho]

I understand the motivation and all my PrusaI3 have alu frame however this project cost estimate is made in mind to use 6mm ply cut on the laser from the space on a do it ourself basis the frame once assembled and with a coat of paint to seal it offer a good platform to complete the cheap Prusa in a reasonable amount of time.
If some of you want to go for the alu options go for it but bear in mind that it will be outside of the scope of that cost estimate

presumably 6mm alu. would be ideal, but depends whether welds are needed. @laurent_muchacho?

Based on the current blueprint only M3 20mm socket screw and nuts are required.

This thread is getting off topic from the initial discussion so please be patient the project post will be submitted in the next few hours

[laurent_muchacho]

To anyone interested in the build I’ve created a project post and the associated call for subscription

[RichM (Rich Maynard)]

Do you have this as a dxf?
