I tried an idea I had for cheaper wheels, printing them out and putting heat shrink on them.
I took the #OpenBuilds .slprt file for their wheel and used #Onshape to modify it slightly for the heat shrink and bearing fit. It felt slightly bumpy on the v-slot even after sanding before putting on the heat shrink. Also it might not be perfectly 45 degrees on both sides because one side was an overhang.
Printed in PLA at .2mm layers. I guess it wouldn’t save that much money in the end but it was fun testing it out.
@raykholo well it printed fine, it’s just the sides aren’t quite the same. So @Electra_Flarefire 's suggestion would be to print two halves separately in the same orientation and put them together to ensure they both have the same angle.
Has anyone tried to make tyres/wheels from an OoGoo substitute like this:
Essentially it’s standard 100% sillicone caulk plus cornstarch powder to make it hand-workable.
I imagine that pressing this oogoo substitute into a 3d printed negative mold of the tyre shape, and then letting it cure overnight might do the trick too…?
@Nazar_Cem I think your onto something using heatshrink for this. It’s consistent, it’s smooth and it’s strong. Especially if you use the glue-lined stuff. It’ll give just enough play to make it smooth/grippy without making it squishy as it’ll have the hard ABS/PLA core.
Printing it in two parts, each having a ridge to catch the bearings so when assembled, the bolt it’self pulls the two halfs together, THEN putting the heatshrink onto should make it as good as it can be. This also puts the join in the center where it won’t effect anything.
