My children wanted bunk beds for their dolls and toys and my 5 year old specified a ladder and a slide so here we have a basic bunk bed set up with ladder and slide. 

You will have to scale the parts to suit your needs and likely you will want to modify the bunk beds to reduce material used.

I scaled mine to an internal top bunk measurement of 150 mm while selecting all parts. 

The slide I had to cut in half and add connectors. 

I made the bad sections chunky so the kids were less likely to break them within minutes. 

I am sure thy will find some dolly blankets and fabrics to make the mattresses and bedding out of. 

I have left it so the posts just slot in and out of the top and bottom so they can pull it apart or have the beds side by side if they wish and there and grooves for the ladder to rest in to make it easier to stay still while playing. 

The slide has ended up being quite big! Im sure they wont mind ;-)

Well my print had a few accidents. Left overnight but had the print bed the wrong way around so it didnt stick and i ended up with bent beds. Kids wont care but gutted they didnt turn out better for the first print. Also it used alot of filament so i think it needs a remix to reduce the bed base heights as they are chunky at 20mm!

Also for the kids i sped up printing the slide in two parts. That also came out huge and I had an accident with the snap clips so had to glue it and the two dofferent printers and different filaments look rubbish but the slide fit and works perfectly. 

If i print again i will use the elegoo and keep the multi colour. Though as predicted. My kids didnt care lol
