i use cura slicer with my ender 3 and you can open a file twice (or mas many times as you like) on the same work area and then slice and save as g code for printing. You are able to move the objects around so that they fit within the printing area. MickyT Thanks Micky - sounds like I need to grab a copy of Cura. Tony Can't get two copies of the model to fit on the bed unfortunately - obviously need a bigger printer already |

7227 forum posts 21 photos | If Tony's lamination pouches are distorting, why not put then through the laminator first of all to change them to transparent sheets? Then they can be punched, and hopefully will fit to the framework without so much of a bulge. Vacancy for proof reader!. Howard Edited By Howard Lewis on 03/04/2020 12:51:44 |

Can anyone else see what is wrong in Ron's picture... Neil Just fine if you want to print in Australia |

Then they can be punched, and hopefully will fit to the framework without so much nf a bulke. Howard It's OK Howard - it had been through the laminator. The problem was with the registration of the punching holes, nothing more. Problem fixed now because I have been donated some OHP transparencies that do the job very well. |

Yes .... but will it let you "interleave" them as opposed to placing them side-by-side? I must try that with Cura. Hadn't thought of that aspect when I commented. If not, it would need to be done at the CAD level I guess, producing an STL that has both. Edited By Bandersnatch on 03/04/2020 16:01:29 |

This version is suitable for a standard UK 4-hole punch: https://www.dropbox.com/preview/Public/Visor_frame_EUROPE_80mm_4hole_v1.stl?role=personal This version is suitable for use with a standard 2-hole punch set to "A6" - punch twice from either end of the long edge. https://www.dropbox.com/preview/Public/Visor_frame_EUROPE_ISO838_v3.stl?role=personal Cheers, Tony |

![]() 154 forum posts 14 photos | Good evening Tony many thanks for the links, but when I go to them I have to register and the first thing they want is access to my contacts..... No Way... I searched google and think that I have found the same frames stacked up. The files show you can print 2, 5, 10, items on top of each other. I have tried slicing a couple of the files with Cura using my machine settings (slow) and 5 frames in 5 hours 10 frames in 11 hours. I will try printing 5 out tomorrow and see what I get...If the stl. file works I will try to upload a non invasive link. John |

I did try this and Cura does allow it in both the current (4.5) version and an older (15.04.6) version. |

7517 forum posts 20 photos | Apparently you can make up to 6 in a stack (of the Prusa design). I’m trying one on a raft tonight as this afternoon's effort came loose from the bed at about 5 1/2 hours (of 6 1/2). Says 17 hours for a stack of four, I think. I expect that is subject to shortening a bit by the 3D printing experts? |

![]() 569 forum posts 20 photos | I've printed 9 today, no raft, direct onto the Ender's heated glass bed. I'm finding that mostly they stay stuck, but release by themselves as the bed cools at the end of the job. Only one failure - one of the arms came unstuck and there was no option but to abort the print. The first one I printed onto a raft but it took twice the material and twice the time, and parting it from the raft wasn't clean or easy. |

7517 forum posts 20 photos | The one I did earlier (from the other thread) was reasonably quick and did not need a raft. It is just that if I am going to make a whole batch of these, in sets if six at a time, I don’t want any mishaps if I can avoid them. They take 55g of plastic each. I will revert to a simpler/quicker design if they are approved for NHS use (somewhere!). |

![]() 19226 forum posts 749 photos 86 articles | I'm printing the Prusa design in about 1 hour 20. Got stuck at 12 because after a filament change they kept coming loose on the right, I've just (finally) realised I broken a connection for the right hand built plate fan, shows how important those tiny fans are!

I've occasionally had trouble with a print coming loose from the bed too. I increased the extruder temperature by 5 degrees and the problem seems to be solved. With a glass bed the surface needs to be cleaned with an alcohol solution sometimes too. It's easy to touch it with your hand when you remove a print and transfer just a little skin oil. |

Indeed...I put my one failure so far down to that - cleaned the bed down with Meths and it has been fine since. I am taking care not to touch the bed when removing parts now. |

152 forum posts 6 photos | Nowadays I only tend to print with ABS+ on a glass bed and find that if I paint the bed (when cold) with a dilute solution of ABS dissolved in acetone that I get no problems at all with adhesion (or lifting) without the need for a raft or anything else. As the things I print are generally exposed to water and need to be quite tough I find ABS+ to be the best medium. Obviously the need to clean the bed with acetone is required occasionally if the layer builds up to much on the bed. I also find that using a bed temp of 110deg C to be best.
