Installed... but le sigh... guess I measured badly. Off by like 2mm and didn’t clamp. BUT had this random bit of scrap plastic lying around because I’ve been lazy about tossing stuff. This was tie down strap for a set of socket wrenches I bought recently and only just opened.pic.twitter.com/PteeT3qe3o
So cut off one of those stemmy bits and jammed it into clearance space. Perfect. The whiteboard even happens to have grooves there that make it fit neatly.pic.twitter.com/2WIvMBJse5

Cheapest I found on amazon is $14.95 for a 10-pack, so $1.49... so this is about 33% cheaper. Plus I only need to print 1 and don’t have to buy 10. The singles are really expensive and most are 4 packs at least.https://www.amazon.com/Stoppers-Minimalist-Neoprene-Resistant-gripping/dp/B07YD58YLQ/ref=sr_1_24?_encoding=UTF8&c=ts&dchild=1&keywords=Door+Stops&qid=1598935129&sr=8-24&ts_id=1069196 …

Even with a reasonable printer amortization schedule over 10 kg, still works out pretty cheap. $1.82https://twitter.com/vgr/status/1300659116935753730 …

Even I have been fancying dabbling with 3D printer (in India) mainly to assuage my desire to get into robotics. The parts are somewhat expensive in small quantity. How steep is the learning curve on 3D printing? For example, rover chassis, some small gears, linkages, maybe?
If you have some existing CAD experience, pretty short. OnShape is free. I’m a mechanical engineer by training, but this is the first time I’m touching the tools in 23 years, got back in fairly easily. The print process is fiddly and takes some trial and error to learn.
Many thanks! I guess I should probably get started slowly and build some hands-on knowledge on CAD tools before investing in the printer itself. (The purchase most likely will happen as an impulsive buy if the enthusiasm with CAD tools boils over :-P)
Yeah make your rover in OnShape first, then get a printer
