Hardware Second Hand

I am planning on getting myself an Anet A8 for Christmas and before someone kicks off suggesting other printers I should probably say I am looking forward to slowly improving this by printing modifications and extensions. Besides I just can't afford the original Prusa i3 I would like.

Anyways It is that tinkering experimentation that I am looking forward to doing.

You should also note I am a keen recycler.

I have been looking on ebay for second hand parts to enhance my tinkering experience, in particular I am looking for Anet A8 printer frames where the original owner has upgraded from their original acrylic frame to one of the other materials. Or given up on getting their printer to work and decided to get an original Prusa i3 Mk3

There’s the option of finding a couple of broken frames and building one working frame from two or more broken ones or using the frame as the core of a Dolly.

Am I looking in the wrong place?

Acrylic isn't great for printer frame and I would suggest other alternative instead.
If you know local shop nearby that can CNC cut at affordable price then aluminium or wood should be better choice.

Or if you can buy aluminium extrusion easily then CR-10 style frame might be good as well.

Lack of cash plus a desire to up-cycle unused kit is my driving force here.

As for acrylic being a bad option, I want to look at finding ways to make acrylic stronger by modification and to come at that from an existing out of the box acrylic frame.

That is to say you can make an acrylic frame stronger by cutting it differently so that you leave more material.

That is not an option if your start point is an original kit. ;)

And OSB is like in everything, so look at recycling old ikea type furniture that people put out for trash.
Look for tv stands, entertainment centers for glass, obc, etc.
Or local thrift stores for old printers and computer parts for motors, wiring, power supplies.

I would think ebay the only place you would find old acrylic frames that people replaced. You may need to put up a standing request on forums, or facebook that you would take these broken and unused parts. Most people probably dont think anyone could use a broken piece.

Once you get 2 sets, you could start cutting up the broken or spare parts and gluing them back together. I think MEK welds acrylic right? If not, careful drilling and bolting of patches should get parts back together.

If you’re buying a second hand prusa frame, why not get a real i3 water cut aluminium one? People who have upgraded to haribo/zaribo often sell their frames.

Over time you could evolve your dolly into a pretty respectable clone.
