When I was 12 I bought a toolbox and started filling it with the things I used the most. Ten years later, here's what's in the toolbox I always take with me:

• Paperclips (small & large) - Never underestimate the utility of long, poky things. I keep some on my keychain, as well & use them often.
  
• Leatherman - This gets the most use out of any tool I own. I usually keep it in my backpack.
  
• Handheld blowtorch - Good for lighting candles, inspiring fear.
  
• 2-part, 5-minute epoxy
  
• Marine epoxy - Has the consistency of clay, but hardens even underwater. Can be used to fix cracked or leaking pipes in a pinch.
  
• Duct tape
  
• Hemostats (curved & straight) - A must if you ever work with small things. They can clamp down to hold two things together, freeing a hand up.
  
• Dinky drill - Get one of these. At first I thought it was lame, but having a small, cordless drill around for quickly disassembling things and drilling small holes saves a lot of time & effort.
  
• Zip ties (small, large) - These are light and very strong. They come in handy for random things and work like a charm.
  
• Hacksaw blades - Just keep a few in the toolbox. I use them primarily to make lockpicks out of. Wrap a length of cord around half of one and use it to saw through small pieces of metal in tight places.
  
• Lockpicks - Having a set of lockpicks and knowing how to use them can come in extremely handy. I keep a set in my car and another in my backpack. Read the MIT Guide to get started.
  
• Digital calipers - Nice for measuring small things to a high precision.
  
• Goof off - Good for getting random stains out & removing sticker residue.
  
• Masking tape - I use lots of this.
  
• Electrical tape - I don't use as much of this, but you should have some anyway.
  
• Wire strippers - You can strip wire with a knife, but these save time.
  
• Latex gloves - These are light, low-volume, and very useful for working with messy things like epoxy.
  
• Rubber mallet - This is one of the first things I bought, and though it doesn't get as much use as most of the other tools, I've never regretted buying it.
  
• Sharpie markers - You always need them, and you never have them. Keep some in your toolbox & away from your desk so they don't get ideas from your ballpoint pens & walk away.
  
• Needle & thread - Good for fixing popped buttons and such.
  
• Microfile set (also called Jeweler's files) - These come in extremely handy when working with small things.
  
• eXacto knives - Everyone should have a set of these.
  
• Carpenter's triangle - Very useful for woodworking. This can save you a lot of time if you learn all its uses.
  
• Hand drill - I just picked this up recently, but it's come in really handy for precision-drilling small holes or pilot holes.
  
• Channel locks - These will hold you off until you have the space & money to buy a full wrench and socket set.
  
  There's a few other things that don't fit in my tool box but I feel should be mentioned:
  
  
• A good, 1/2" CORDED drill - Don't skimp here. Cordless drills have rechargeable batteries that always wear out and need to be replaced. Use the dinky drill for those kinds of jobs. If you buy a nice corded drill & clean it occasionally, you may never have to buy another one again.
  
• Rope - I keep a good length of rope in my car & have used it many times.
  
• Steel coat hangers - These are terrible for hanging clothes, but they can be used to make all sorts of things.
  
• Dremel tool - You can do anything with a dremel tool and enough cutoff wheels.
  
• A hand saw - You can cut pieces of wood pretty precisely with a good hand saw & a little practice, and it's much more compact than the equivalent power tool.
  
• Towel - No explanation needed.
  
  Anyway, these are the things I've taken off to college with me, and they work for 98% of all the jobs I've needed to do over the past four years. Anyway, hope this helps, and good luck to you.

Hope this helps
2 12V Photoelectric relays
12V motor
6mm bore pully to match motor shaft
Project box
2 limit switches
Solar panel
Battery
If not solar powered. Aka no solar panel or battery

If you have any other questions let me know I am at work and I will answer what I can on my phone

Edit: I forgot a pully to run the rope from, but the motor I linked has so much torque you could go direct no problem, and lumbar to build the door. I estimated about 10$ for wood. I used all treated, as that's what I had laying around, but its probably not necessary as most of the door on my design was in the coop. I can make you a wiring diagram as well if you are interested. That reminds me you should use 4 zener diodes (just because you only need 4 doesn't mean you shouldn buy a 100 for future projects :) also if you goto an electronics store you will pay 5-6$ for 6 diodes) to stop flash back through the whole circuit from the reversing of polarity with the motor.

For the Y-idler you can use any 6mm-wide flanged bearing with a 3mm bore. I use these. I'm not sure on the springs, but if it's anything like a Greg's Wade extruder it should be ~5x15mm, spring rate doesn't matter too much. The LCD is a RepRapDiscount Smart Controller, available from any one of a number of sources.

Wonderful thank you!

Would these be the right belts (and enough length)?

Yea I agree. I can see why people would think you're "hating" on the printers, but I honestly see you trying to warn and help out the new guys.

I agree it's not "Tinkering" and can very much be a shit load of busy work that should already have been done by the factory, but I'm a weird person and like that crap :P

The most important thing I'm keeping in mind is simply this: If it turns out to be a 100% all-around shit experience, that's my fault and it's not typical of all 3D printers.

Thanks for all you do and keep putting out the good words!

I'll second the printrbot play.

I use a printrbot play, and I'm very happy with it. $400 entry level printer, recommend a y-axis upgrade and a zebra-plate from printinz. I also use hatchbox filament from amazon.

You could realistically increase the Y axis with only two longer 8mm rods, a printinz plate of equivalent length, and a GT2 belt.

Long detailed post about it here:

That's not to say there aren't problems and heartaches with every 3D printer. It's still an emerging technology. There are tons of issues that can happen. I recommend shopping not only for a printer, but also a printing community.

1 is a common belt pulley:

2 is a another simple pulley used for rope or a clothesline:

3 is a chain boomer... used during transportation when a chain is used to tie something down

4 is a manual drill

At one time, Cisa was a player in this lock genre. Here is an example.

I had the same thing happen to me. ALWAYS use a D-lock! I know I will from now on. The thief didn't even need to cut it; if he was patient, he could have just tried each of the 10000 combinations and it would have taken him a maximum of about a few hours to crack. That lock was a deterrent at best.

But hindsight is 20/20, and I'm very sorry for your loss. Keep your eyes on ebay and gumtree, and also preloved, for bikes.

To everyone else: ALWAYS use a D-lock. Most cable locks are useless, unless they're >15mm thick. If a thief wants your bike and it has a cable lock, all they need is a strong hand and a pair of sacateurs in most cases

My new lock. I'm not taking any chances

Lowes. Stanley National Hardware 3219BC 1-1/2" Zinc Plated Wall/Ceiling Mount Single Pulley https://www.amazon.com/dp/B000FPDGA6/ref=cm_sw_r_cp_apap_yVJBy6uOGS7UT the pulleys are pretty much those. Similar price too.

It must be a pain in the but having to spin that nut on and off the bolt every time.

I know you didn't ask for my advice but I think that Drawbolt latches will be equally secure if not superior to your current latch setup, but much easier to open.

If you still want to have the ability to throw a padlock on the case you can always buy draw bolt latches with the eyelet for a pad lock.

Thank you for your help. And I hope you liked my idea in return.

What about something like this?

Although, with that price... maybe I will just go with a torque wrench. Do you recommend a torque wrench specific for auto applications like this?

It's pretty easy to make your own "kit" if you have the BOM and access to Amazon or a site like it. I'm biased because I've always gotten good service from them. Some people have said that I'm biased because they pay me, but I really do try not to recommend places of business that I don't frequent myself.

Anyhow, here are the x upgrade and the y upgrade that I was looking at when I went searching.

Both use 608 bearings and a 10 pack should take care of it and give you several spares for further upgrades or replacements in the future. (want a spool coaster?)

Next you need the GT2 belt and 2 pulleys. Done.

The BOM doesn't say it, but you might need some m3 screws

Edit: Full disclosure: Amazon pays me something like 4% on items that aren't sold by third parties. If everything on this list qualifies and you buy it all I expect to make about a dollar.
