3D printed MGF / FT items bits added

Had a pretty good result selling bits on a FB forum thought i'd try it here too, doing seat belt guides at £15 per pair inc p&p, Cup holders 2 styles Drop down ones £14 inc p&p, Centre console ones @£16 inc p&p, Tyre valve caps various colours At £7.50 inc p&p, All p&p is uk mainland other areas i'll work out a cost
 
 
   

 
 

One comment on your rather excellent belt guides is the need to trap them beneath the head rest. If you need to have the restraint higher, the guide would be loose, unless the holes are interference fit.
A collar with a set screw supply separately or integral with the print would be an asset.
The domed covers on the restraint supports can get tatty for some reason, replacements might be interesting.

thats not a bad idea, could tap them and supply a 6mm bolt
 

An M6 screw might take too much meat from the plastic requiring a more robust assembly (more plastic to print). All you are doing is positioning & securing the assembly, not bolting it on, an M4 would be adequate.
Granted the thread form won’t be as robust & you must inform your customer not to go at it with a windy gun, although there will be some tit - - - -.
With stainless grub-screws & a cheap Allen key supplied it could be an nice side hustle. 
Give it a run & if you want a more robust assembly you could always adopt tapped brass inserts. 
Just a thought.

Afternoon Everyone
been tinkering with the 3D printer and designed these alternative sun visor extensions 2 different designs with logo's and one plain design, tested on mine and they fit nicely

 

Those sun-visor extenders are very smart!  I broke the drivers side about 3 miles into my very first journey.  I have managed to source a new complete sun visor, with a good extension, but I get very nervous whenever I see my passenger deploying the visor extender on their side!

How much are you charging? assuming you are prepared to sell these??

I've got them on marketplace for £16 plus p&p a set with the logo but to members here £12 a set plus P&p

Had a friend print these off at the weekend for me, think the solid one might be less liable to break and I've lost the spring along time agk
