Here is an openscad file for a marker holder that we could screw on all the whiteboard, the idea is this would go on the side so the markers are held horizontal sticking out from the plane of the whiteboard (to avoid screw into the whiteboard itself, but that might be an option)
Anyone interested in printing these out and attaching them to all the rolling whiteboards?
Of course the awesome thing about openscad is the file is all parameterized, so making a 100 marker holder for 1mm diameter markers is just editing two numbers and hitting F6 then export stl.
All the settings should be good, I printed one out a long time ago at the 17.5mm marker diameter and it worked. I just guessed at the 3.5mm screw diameter, might have to measure the screw to use.
I printed out one but the 17.5mm inside radius was a bit too loose for my liking (it fit the fat part of the marker well enough but not the skinny part) so I settled on 17.2mm inside radius which held the fat and skinny parts of the marker equally well with a satisfying click. Ya, the screw diameter fit some standard wood screws in the warehouse (that we seem to have by the bucket-full). I haven’t gotten them on every markerboard yet (and what I’m doing is drilling it so that the markers are always available on the left side of the marker board if it’s facing you; so each marker board gets a pair of marker clips).
Thanks! Allen really liked the one you posted so I went ahead and started 8 more for him to mount around the space. I decreased the inner radius to 17mm and increased spacing between holders to 5mm
@uglyknees The gcode or the stl file? To generate the most up to date stl you can download OpenSCAD and use the text in the initial post that I have been updating the parameters in.
Here is the STL using the parameters that Brandon sorted out (17mm inner radius and 5mm holder spacing). Dropbox
@Brandon_Green I’ve been thinking about learning the scripting language in OpenSCAD (it reminds me of PHP with not having to initialize variables but I see some array declarations like C+). I think the first project that I’m going to work on is to add a hook for erasers (and drill a hole into the eraser or attach a hanging clip to the eraser) to the bottom of the marker clips (with variables like height, width, depth, circle degrees (for how open the hook is), flat section (for a space that the eraser can snugly sit on), hook offset (how far below the clips the hook is), and hook direction (top or bottom in relation to the screw holes)). Are there any tutorials or references that you could point me towards?
I’d like an OpenSCAD class if someone is an expert, I definitely want to learn it as well, but I don’t have a programming background so I might find it more difficult.
An eraser holder would be great, a kind of C clip might also hold the erasers, someone stuck an iPhone case onto one in the main room which could be a template
Other than just reading the OpenSCAD wiki I have only ever made a few things. You just start with one primitive shape, then translate/rotate it around, then either union or difference another shape one piece at a time.
