I'm developed and design roller system - fitted to case W: 28cm H: 28cm, because many plastics bags with breads looks horrible!
Now my kitchen looks more luxury! No more bags looks out from the case!
I'm tried to do an optimized shape for 3D printing, especially is setup for 0.4 nozzle system. 2 times drive around the shape and next layer. Optimized for the nozzle, speed, material needs.
You can find parts:
1 Guide: rails, turns, ends
1 Roll: Mainpart, Holder+end, Closure End part
I made a bigger portfolio of formats for you. Designed in Autodesk Inventor.
Formats: .igs, .stp .ipt
Version 1: Shape = S / 0.8mm of Shell / no problem for printing stability!
Version 2: Is not stable for printing, in higher positions is melted by the extruder. I will work on it to optimize!
Printing time and process:
Based on quality what was required is printing time really low and used a middle fan. Bigger transport speed can drop down the parts, especially big risky is in the higher places of the part!
Material: Colorfabb black PLA
Temperature: between proposed temp from producer of material
Time: 1Roll: 3,45hours
I advise doing bigger BRIM for better sticking to bed.
ROLLS: 32 + 2 holders + 2 closures
GUIDE RAILS: 12 mid + 12 end + 4 turn
In total aprox 70 hours of printing.
So, I hope that will helpfully also for your open cases at your home!
In further question feel free to contact me.
Would be nice if you will connect on my facebook page, which is actualized with freshly printed things and photos!
