Full Version: New Classic Battery Cover Latches For Sale
You're currently viewing a stripped down version of our content. View the full version with proper formatting.

I am in the process of making new plastic latches for a classic series calculator.

These will be made via a rapid prototyping machine and made in a structural plastic. Drawback is the natural color is white. It can be painted to match various models.

I am posting this to gage interest in the forum as I am willing to make up more than the two I need. Price is TBD at this point as I have not finished them to determine total costs. I think they could be in the 30-40 range for a pair. Are people willing to pay this for new latches?

I can make 2 versions - 1 with cutout for rubber feet. Another made from solid plastic if your feet are missing.

I am also seeking to gage interest in the production of other like parts for other models. Drop me an email if you are interested.

Peace,
Adam

Yes please Adam, I'd been keen for 8 - 10 assuming price will be a few $$$ each.

Cheers,
John

is what I quoted "a few"? I am not looking to get rich here, but some of the processes that I am experimenting with are expensive, others are not quite so. One that could give me a black part without painting is much more expensive than the white version I would need to paint.

would you want to pay less for unpainted versions and you finish?

I'd be interested but not at those price points.

I've only got one classic and it is missing one of these feet/latches.

Thanks, keep the requests coming. The more I see, the better chance I have at getting the prices manageable. I'd like to be in the 10-20 RANGE per. Does that sound attractive?

I would order about 5 pairs, more if the cost could come down! I would finish in the correct colour. Also they would be the ones without the rubber cutout as I would insert new rubber myself.

I'ld like 3 pairs if the price was in the 10-20 range, preferably with the cutout for rubber feet, white OK.

Best wishes

If the price goes down, I would order few pairs myself, but, how can these pe painted and how can the rubber feet replaced ? take care Alberto

I would purchase a few myself. I would need to paint them black.

The hp third generation Hp 31E to hp 38E were notorious for losing the battery covers. Myself I have 34E without battery cover. I have been looking for one to show up in ebay for a long time but no luck..

Ok here's the deal.

I got these working tonight. I'd like to offer them for $15 a pair without paint + shipping. My first batch required a little sizing with an exacto knife and a nail file. I will tweak the CAD model so this is minimized in future builds. However, I beleive it is better to have too much material than too little so I will leave some material to be filed.

If you want a pair please send $16.50 to my Paypal account: adamjjones@adelphia.net

I am open to making other plastic items for restorations, but I need good samples to copy.
