it is not beautiful, but it is working!
i use it from time to time at work. it can carry my laptop without any problems and my working laptop is pretty heavy (2,9kg). i am pretty optimistic that this holder can hold also laptops that weight around 4-5 kg but i haven't testet it yet.
KNOWN ISSUES:
- risk of squeezing your fingers
when you attach the holder to a surface, be aware of your fingers, as you may squeeze them
- no dedicated feature for transportation
at the moment you can use the rope to carry the holder, but its not perfect
- risk of sliding while using
try to maximise the friction between the magnets and the surface. i applied insulation tape on the magnets, that did the trick for me. Your “friction enhancer” should be as thin as possible!
BE AWARE that this system relies on the friction between the surface and the magnets! if the magnets and/or the surface that you want to hold on is too slippery, then the holder will just slide down at the surface. the magnets must hold the "shear forces" between holder and surface and these forces rely only on friction.
Printsettings for my Prototype:
8 perimeters
15% infill
PETG recommended
alignment for all parts → nut opening is pointing upwards
feel free to experiment and share your settings!
Feedback is very welcome!
BOM:
1pc of each stl file of this model
1m 4mm rope (4mm is the maximum, less is possible)
3x M6x14mm countersunk head screw (for the magnets)
20pc M4x40mm cylinder head screw (or other flat head) e.g. DIN 912
14pc M4x60mm cylinder head screw (or other flat head) e.g. DIN 912
34pc M4 square nut DIN 562 (2,2mm thickness)
2pc M5x60mm cylinder head screw (or other flat head) e.g. DIN 912
2pc M5 Nut (will be fixed with glue) or ruthex M5 melting inserts
3pc Neodymium flat pot magnets Ø 36 x 8 mm, with screwed bush
(i used these Neodym Flachgreifer Topfmagnete D36x8 mm Gewindebuchse 41kg - these magnets have a pretty smooth surface - you need to apply some friction enhancer)
you can use any other magnet, but then you have to adapt the mounting of the magnets. the neccessary fusion files are also added.
planned updates:
- carrying handle
- safe position for the fingers when attaching to a surface
- adjustable angle
